Resumen

Objetivo: comparar las restauraciones realizadas con resina FILTEK TM Z350XT vs resina Micerium. Método: Revisión sistemática en 25 articulos. Resultados y Conclusión: La resina FILTEK™ Z350XT se posiciona como una opción superior en restauraciones dentales debido a su alta resistencia mecánica, estabilidad de color, durabilidad y capacidad para mantener propiedades frente a desafíos químicos y manchas, además de su potencial para ser modificada con rellenos antimicrobianos. Estas características la hacen ideal para restauraciones en zonas de alta carga funcional y estética. Por otro lado, aunque la resina Micerium presenta un desempeño aceptable en aspectos como estabilidad de color y coincidencia cromática, su efectividad está más condicionada por factores externos como el tipo de pulido y el método de selección de color, lo que podría limitar su predictibilidad en ciertos casos.

Resumen

ABSTRACT Objective: The aim was to evaluate the effect of different adhesive systems and surface treatments on the integrity of resin-resin and resin-tooth interfaces after partial removal of preexisting resin composites using quantitative image analysis for microleakage testing protocol. Materials and Methods: A total of 80 human molar teeth were restored with either of the resin composites (Filtek Z250/GrandioSO) occlusally. The teeth were thermocycled (1000×). Mesial and distal 1/3 parts of the restorations were removed out leaving only middle part. One side of the cavity was finished with course diamond bur and the other was air-abraded with 50 μm Al2O3. They were randomly divided into four groups (n = 10) to receive: Group 1: Adper Single Bond 2; Group 2: All Bond 3; Group 3: ClearfilSE; Group 4: BeautiBond, before being repaired with the same resin composite (Filtek Z250). The specimens were re-thermocycled (1000×), sealed with nail varnish, stained with 0.5% basic fuchsin, sectioned mesiodistally and photographed digitally. The extent of dye penetration was measured by image analysis software (ImageJ) for both bur-finished and air-abraded surfaces at resin-tooth and resin-resin interfaces. The data were analyzed statistically. Results: BeautiBond exhibited the most microleakage at every site. Irrespective of adhesive and initial composite type, air-abrasion showed less microleakage except for BeautiBond. The type of initial repaired restorative material did not affect the microleakage. BeautiBond adhesive may not be preferred in resin composite repair in terms of microleakage prevention. Conclusions: Surface treatment with air-abrasion produced the lowest microleakage scores, independent of the adhesive systems and the pre-existing resin composite type. Pre-existing composite type does not affect the microleakage issue. All-in-one adhesive resin (BeautiBond) may not be preferred in resin composite repair in terms of microleakage prevention.

Resumen

Abstract Objectives This study was aimed to determine the effects of modeling resins on the surface microhardness of composites. Materials and Methods Six resin-based composites (Charisma Smart, Estellite Asteria, CeramX-One SphereTEC, Admira Fusion, Filtek Ultimate, and Clearfil Majesty Es-2) and three wetting agents (Modeling Liquid, Composite Primer, and Modeling Resin) were investigated. In all, 240 specimens were prepared, and wetting agents were applied prior to light curing in the experimental groups. After 24 hours, specimens were polished and Vickers microhardness (VHN) values were measured. Statistical Analysis Shapiro–Wilk and two-way analysis of variance (ANOVA) were used for analyses (p < 0.05). Results Both modeling resin and composites were determined to be effective factors (p < 0.001). The control group showed the highest VHN (70.37 ± 7.94), followed by Modeling Liquid (64.68 ± 12.07), Composite Primer (59.84 ± 6.33), and Modeling Resin (58 ± 3.52b; p < 0.001). Filtek Ultimate showed the highest VHN (76.62 ± 9.78c), whereas Charisma Smart (58.87 ± 7.95), and Clearfil Majesty (67.27 ± 2.58) showed the lowest (p < 0.001). Clearfil Majesty–Modeling Liquid (46.62 ± 5.33) and Charisma Smart–Composite Primer (50.81 ± 0.39) combinations showed the lowest VHN, whereas Filtek Ultimate–control (87.15 ± 2.12) and Filtek Ultimate–Modeling Liquid (84.24 ± 3.11) showed the highest (p < 0.001). Conclusion All tested modeling resins decreased VHN value, and the amount of reduction varied among composites and wetting agents. It might be safer not to use wetting agents unless they are necessary.

Resumen

Innovative polyethylene films are constantly being developed by switching the existing or incumbent resin with a new or challenger resin. If the extrusion equipment is designed properly, the film with the challenger resin will be acceptable for further testing and marketing. However, if the extrusion equipment is not designed properly, old degraded material from the incumbent resin will be pushed out of the extruder by the challenger resin, contaminating the test film. In many cases, the challenger resin is incorrectly blamed for the gels. This paper describes the incumbent resin effect, presents a case study, and provides technical solutions.

Resumen

<strong>Abstract</strong> <strong>Introduction</strong><strong>:</strong> This in vitro study evaluates and compares three denture cleansing methods in the removal of tea, coffee stains from conventional and high impact polymethylmethacrylate heat cured denture base acrylic resin.    <strong>Materials & Method</strong><strong>:</strong> Two types of denture base acrylic resins were polymerized into 360 specimens, 30x8x2mm dimension each. Samples were treated with 300ml artificial saliva and distilled water and air dried. Beverage decoction was prepared for sample staining using distilled water under controlled conditions. Each stained samples are subdivided into three groups of 30 specimens for each kind of cleansing method, tablet (Secure Denture Tablet Group Pharma Pvt Ltd),ultrasonic cleaning (Confident ) & both tablet & ultrasonic method. The values of spectrophotometer are obtained from the samples before, after staining & after cleaning. The results averaged & mean derived. Stains on each of the denture base resin were analyzed (using ANOVA test) for cleaning. Comparison of each stain for denture base resins was done by ‘Z –Test’. <strong>Result</strong><strong>:</strong> Tablet and ultrasonic cleaner showed a maximum cleaning ability, while tablet performance as a cleanser was better considering ultrasonic. The tablet cleanser is better because of sodium perborate monohydrate, releasing nascent oxygen with better cleaning effect. <strong>Conclusion</strong><strong>: </strong>Routine cleansing of dentures by denture brushes’ and detergents can remove only surface stains and not deeper level stains. The present study promotes usage of chemical method only or chemical & mechanical method for better maintenance of the dentures.

Resumen

The aim of this study was to evaluate four test methods on the adhesion of resin composite to resin composite, and resin composite to glass ceramic. Resin composite specimens (N = 180, Quadrant Universal LC) were obtained and distributed randomly to test the adhesion of resin composite material and to ceramic materials (IPS e.max CAD) using one of the four following tests: (a) Macroshear SBT: (n = 30), (b) macrotensile TBT: (n = 30), (c) microshear µSBT: (n = 30) and (d) microtensile µTBT test (n = 6, composite-composite:216 sticks, ceramic-composite:216 sticks). Bonded specimens were stored for 24 h at 23 °C. Bond strength values were measured using a universal testing machine (1 mm/min), and failure types were analysed after debonding. Data were analysed using Univariate and Tukey’s, Bonneferroni post hoc test (α = 0.05). Two-parameter Weibull modulus, scale (m), and shape (0) were calculated. Test method and substrate type significantly affected the bond strength results, as well as their interaction term (p < 0.05). Resin composite to resin composite adhesion using SBT (24.4 ± 5)a, TBT (16.1 ± 4.4)b and µSBT (20.6 ± 7.4)a,b test methods presented significantly lower mean bond values (MPa), compared to µTBT (36.7 ± 8.9)b (p < 0.05). When testing adhesion of glass ceramics to resin composite, µSBT (6.6 ± 1)B showed the lowest and µTBT (24.8 ± 7)C,D the highest test values (MPa) (SBT (14.6 ± 5)A,D and TBT (19.9 ± 5)A,B) (p < 0.05). Resin composite adhesion to ceramic vs. resin composite did show significant difference for the test methods SBT and µTBT (resin composite (24.4 ± 5; 36.7 ± 9 MPa) vs. glass ceramic (14.6 ± 5; 25 ± 7 MPa)) (p > 0.05). Among substrate–test combinations, Weibull distribution presented the highest shape values for ceramic–resin in µSBT (7.6) and resin–resin in µSBT (5.7). Cohesive failures in resin–resin bond were most frequently observed in SBT (87%), followed by TBT (50%) and µSBT (50%), while mixed failures occurred mostly in ceramic–resin bonds in the SBT (100%), TBT (90%), and µSBT (90%) test types. According to Weibull modulus, failure types, and bond strength, µTBT tests might be more reliable for testing resin-based composites adhesion to resin, while µSBT might be more suitable for adhesion testing of resin-based composites to ceramic materials.

Resumen

AbstractIn this paper an attempt has been made for linear and non linear modeling of resin bonded sand mould system using full factorial design of experiments and response surface methodology, respectively. It is important to note that the quality of castings produced using the resin bonded sand mould system depends largely on properties of moulds, which are influenced by the characteristics of sand, like type of sand, grain fineness number, grain size distribution and quantity and type of resin, catalyst, curing time etc. In the present study, percentage of resin, percentage of hardener, number of strokes and curing time are considered as input parameters and the mould properties, such as compression strength, shear strength, tensile strength and permeability are treated as responses. In the present work, phenol formaldehyde is used as the resin whereas tetrahydrophthalic anhydride as the hardener. A two level full factorial and three level central composite designs are utilized to develop input-output relationships. Surface plots and main effects plots are used to study the effects of amount of resign, amount of hardener, number of strokes and curing time on the responses, namely, compression strength, tensile strength, shear strength and permeability. Moreover, the adequacies of the developed models have been tested using analysis of variance. The prediction accuracy of the developed models have been tested with the help of twenty test cases and found reasonably good accuracy.

Resumen

Abstract The objective of this study was to develop a performance-competitive bio-based hybrid resin system composed of methylene diphenyl diisocyanate (MDI) resin and novolac phenol-formaldehyde (PF) resin for engineered wood panel manufacturing. A novolac PF resin and a bio-oil–modified PF resin were blended with MDI at weight ratios of PF to MDI of 85:15, 75:25, 50:50, and 25:75, respectively. The obtained hybrid resins were examined with Fourier-transform infrared (FTIR) spectroscopy and thermogravimetric analysis (TGA), and evaluated as plywood binders. The results indicated that the gel times and viscosities of hybrid resins were closely related to the weight ratio of PF resin to MDI. At a ratio lower than 75:25, the viscosities of hybrid resins were appropriate for plywood application. FTIR results showed some reactions between the novolac PF resin and MDI. TGA results showed that reacting novolac PF resin with MDI resin possibly increased the thermal stabilities of hybrid resins in the temperature range of 150°C to 300°C. Panel performance tests showed that blending novolac PF resin with MDI increased both the dry and the wet bonding strength of panels at the optimal ratio of 50:50. Replacing phenol with bio-oil of the hybrid resin had the trend of reducing the hybrid resin gel time and increasing panel dry and wet bonding strength.

Resumen

ABSTRACT Objectives The aim of this study was to evaluate the bond strength of different direct reliners to acrylic resin for denture base. Materials and methods Double-cone specimens were made: HA-heat-cured acrylic resin-(n = 20); U-Ufi Gel Hard C-(n = 10); K: Kooliner-(n = 10); R-Rebase II Fast-(n = 10) and RH-Rebase II Fast + Resin Hardener-(n = 10). Ten HA samples were immediately submitted to cohesive test. The remaining HA samples and others were submitted to thermal aging (HAaged, 1000 cycles, 5.55oC), followed by tensile test. For tensile strength, 50 single cone-shaped samples were made of heat-cured acrylic resin and aged (HAaged, 1000 cycles, 5.55oC). After surface treatment, relining resin cones were build up using silicon molds, and stressed to failure. Values of cohesive and tensile strength were submitted to one-way ANOVA and Tukey's test (α = 5%). Results Bond strength were: HA/HAaged: 21.17 (Â±4.89)a, U/HAaged: 11.56 (Â±1.98)b, R/HAaged: 9.69 (Â±2.37)b, RH/ HAaged: 9.38 (Â±1.78)bc and K/HAaged: 5.98 (Â±1.90)c. The cohesive strength were: KCoe: 22.29(Â±4.06)a; RCoe: 23.99 (Â±3.29)a; RHCoe: 24.84 (Â±3.88)a; UCoe: 25.62 (Â±3.03)a; HAaged: 36.06 (Â±8.65)b and HA:42.29 (Â±7.68)b. Groups followed by the same letters do not show differences. Conclusion Bond strength of acrylic resin to acrylic denture base material is higher than the reliners and Ufi Gel Hard C showed the higher bond strength.

Resumen

O objetivo do presente trabalho foi realizar uma revisão de literatura avaliando o desempenho clínico de restaurações diretas com resinas compostas bulk fill em comparação com as resinas compostas convencionais. Foi realizada uma seleção de artigos científicos nas bases de dados Pubmed e Periódicos Capes/MEC, utilizando os descritores bulk fill resin composite and clinical evaluation, bulk fill resin composite and clinical study e bulk fill resin composite and clinical trial. Foram encontrados sete artigos científicos, correlacionados com ensaio clínico randomizado, publicados entre os anos de 2014 e 2017, dos quais apenas seis foram selecionados. De acordo com esta revisão, a resina bulk fill de baixa viscosidade se mostrou clinicamente melhor que a resina convencional no período de avaliação clínica de um a três anos, para o critério de retenção. Quando avaliada após cinco anos de acompanhamento clínico, mostrou-se com boa durabilidade, porém estatisticamente semelhante às convencionais. Já as resinas compostas bulk fill de alta viscosidade se mostraram tão eficazes quanto às convencionais de acordo com os critérios USPHS (United States Public Health Service) após 12 meses. Além disso, a técnica de aplicação utilizando a vibração sônica não se mostrou estatisticamente superior. Portanto, a utilização de resinas bulk fill, em restaurações diretas de dentes posteriores, apresentou desempenho clínico satisfatório, além da vantagem do menor tempo clínico requerido.Palavras-chave: Resinas Compostas.

Resumen

This study presents a comprehensive examination of Pinus kesiya var. langbianensis (Pinus kesiya var. langbianensis), the primary resin-extraction tree species in Yunnan Province, China. In this study, we formulated different concentration gradients of 0.25%, 0.5%, 1%, and 2% of diquat solution as tapping stimulant to test the effect of different concentrations on the resin gain rate of Pinus kesiya, and analyzed the relationship between anatomical structure, major chemical composition of turpentine and resin yield by methods such as wood anatomy and chemical composition analysis of turpentine. The primary focus of the investigation was on exploring the interrelationships among resin-tapping stimulants, anatomical structures, turpentine components, and resin yield. Research findings demonstrate a significant enhancement in resin production due to the application of stimulants, with the highest increase rate reaching 55% in a specific group, while others achieved approximately 30% increments. Moreover, measurement data about resin duct dimensions indicate a noteworthy increase in resin duct area for the stimulant-treated group compared to the control group. However, it should be noted that the impact on resin duct area by varying stimulant concentrations was relatively minor. Furthermore, continuous observation of resin extraction from different resin-yield classes of P. kesiya revealed insignificant variation in resin yield over time for the low and moderate resin-yield groups. In contrast, the high resin-yield group exhibited a gradual increase in resin production. Interestingly, the high resin-yield group exhibited the smallest resin duct area, but the highest resin duct density, indicating an interconnectedness of resin duct-related data that influences resin yield. Additionally, correlative investigations between anatomical structures and resin yield demonstrate a positive correlation between resin duct area and resin yield, total resin production, and average resin yield. This underscores the importance of resin duct area as a significant factor in resin production. On the other hand, the influence of stimulant concentrations on the turpentine components was found to be negligible. Overall, the correlation results suggest that turpentine components cannot reliably predict or differentiate between high and low resin-yield trees. This study provides a comprehensive analysis of the interrelationships among stimulants, anatomical structures, and turpentine components, offering a theoretical foundation for the resin extraction and resin processing industries in Yunnan Province.

Resumen

INTRODUCTION: Ensuring adequate occlusal contacts and anatomy shape and form is always a challenge when placing extensive direct posterior composite resin restorations. The use of a correct technique, such as, an occlusal matrix can reproduce occlusal morphology more precisely. Additionally, recently, silorane-based or bulk fill composite resin present low shrinkage and were specifically designed for restoring posterior teeth.CASE REPORT: This report presents the clinical application of a low shrinkage composite resin system with a preoperative occlusal matrix in extensive composite resin restoration of a molar with hypomineralization. Acrylic resin was applied over the waxed tooth to copy the anatomic details. Cavity was prepared and bonding system was applied. Definitive layer in the occlusal matrix was applied and stabilized in position. Once curing was complete, occlusal matrix and resin excess were removed using a surgical blade.CONCLUSION: The application of these materials with occlusal matrix can provide a simpler technical approach, saving time and improving esthetic results.

Resumen

Introdução: Habitualmente a conduta tradicional ideal para tratar restaurações compostas insatisfatórias seria a substituição, entretanto, reparo em resina coparticipa da concepção odontológica de “intervenção mínima”. Objetivo: Aprofundar no assunto e avaliar desempenho do reparo (com resina composta) no manuseio em restaurações dentárias de resina composta defeituosa. Metodologia: Foi realizado uma busca em artigos na base de dados PubMed no período 2010 a 2019, com as palavras-chaves “composite resin”,“resin repair” e “microleakage dental”. Discussão: O reparo de restaurações parcialmente defeituosas foi extensivamente estudado e está crescendo na rotina clínica como uma abordagem alternativa. Destaca-se por limitar os riscos de lesões pulpares e preservar as estruturas dentais, minimiza apreensão dos pacientes quanto a dor, ansiedade, tempo e custo. Empecilho para um analise mais fluente são as inúmeras variações nas condições de estudo, por exemplo, diferentes condições de envelhecimento ou tratamentos de superfície adesiva. Materiais, marcas, condicionamento e outros vários fatores influenciam no resultado do reparo, contudo, estudos com resultados em acompanhamento sugerem que o reparo apresenta tanta eficácia quanto a substituição total de restaurações de resina com infiltrações. Conclusão: A proporção desse estudo pode levar a influenciar no financiamento dos dentistas na escolha entre a substituição e o reparo das restaurações.

Resumen

In this paper, under the effect of MD1041 cashew oil modified phenolic amine curing agent for epoxy resin, it successfully prepared polyurethane flexible resin modified epoxy resin composite materials by using polyurethane modified epoxy resin reinforced flexible resin. Modified composite material of the new preparation is characteristed by the method of the mechanical performance test, Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC). The results show that the flexible resin has a strong effect on the toughness of modified epoxy resin composite materials. When the mass ratio of the flexible resin account for 5.9%,comprehensive mechanical properties of the modified composites is at the premium; when the mass ratio of flexible resin account for 3.1%, the thermal stability of the epoxy resin modified with flexible resin is at the best.

Resumen

Although autopolymerizing resin offers numerous applications in orthodontic treatment, plaque tends to accumulate between the appliance and the mucosa, which increases the number of microorganisms present. In this study, we added cetylpyridinium chloride (CPC) loaded montmorillonite (Mont) and nanoporous silica (NPS) to autopolymerizing resin (resin-Mont, resin-NPS) and evaluated their drug release capacity, antimicrobial capacity, drug reuptake capacity, mechanical strength, and color tone for the devolvement of autopolymerizing resin with antimicrobial properties. As observed, resin-Mont and resin-NPS were capable of the sustained release of CPC for 14 d, and a higher amount of CPC was released compared to that of resin-CPC. Additionally, resin-Mont and resin-NPS could reuptake CPC. Moreover, the antimicrobial studies demonstrated that resin-Mont and resin-NPS could release effective amounts of CPC against Streptococcus mutans for 14 d and 7 d after reuptake, respectively. Compared to resin-CPC, resin-Mont exhibited a higher sustained release of CPC in all periods, both in the initial sustained release and after reuptake. However, the mechanical strength decreased with the addition of Mont and NPS, with a 36% reduction observed in flexural strength for resin-Mont and 25% for resin-NPS. The application of these results to the resin portion of the orthodontic appliances can prevent bacterial growth on the surface, as well as on the interior, of the appliances and mitigate the inflammation of the mucosa.

Resumen

AbstractDespite composite resins capacity to mimic dental tissues, they can discolor over time. However, there is no information on the effect of prebrushing mouthwashes on the composite resin staining. This study aimed to evaluate the effect of prebrushing mouthwashes on the color stability of three composite resins. Twenty specimens of each resin were prepared: Filtek Z250 (3M ESPE –S Paul, MN, USA), Charisma (Heraeus Kulzer GmbH - Hanau - Germany) e EvoluX (Dentsply- Petrópolis - Brazil). Groups were randomly divided accord to the treatment: immersion in prebrushing mouthwash (test group) or immersion in deionized water (control group). Test groups were immersed in 10 ml of prebrushing mouthwash Plax Magic (Colgate-Palmolive, São Bernardo do Campo, SP, Brazil) for 60 s three times a day during 35 days following the manufacturer’s instructions. Color measurements were performed after 24 h of specimen’s preparation and after 7, 14, 21, and 35 days of immersion time. Results showed that prebrushing mouthwash Plax Magic promoted a color change in all the tested materials and evaluation time. The color change was greater in composite resin Charisma, followed by Z250 and EvoluX. Therefore, prebrushing mouthwash promoted a color change in all the materials used. Composite resin Charisma demonstrated less color stability than Filtek Z250 resin and EvoluX resin, which was the most stable.Keywords: Composite Resins. Oral Hygiene. Color.ResumoApesar da capacidade das resinas compostas de mimetizar os tecidos dentais, esses materiais podem ter sua cor alterada com o tempo. No entanto, não há informação na literatura sobre o efeito de evidenciadores de placa na estabilidade de cor desses materiais. Este estudo teve por objetivo avaliar o efeito de um evidenciador de placa na estabilidade de cor e três resinas compostas. Para isso, 20 espécimes de cada resina foram preparados: Filtek Z250 (3M ESPE –S Paul, MN, EUA), Charisma (Heraeus Kulzer GmbH - Hanau - Alemanha) e EvoluX (Dentsply- Petrópolis - Brasil). Os grupos foram aleatoriamente divididos de acordo com o tratamento a ser submetido: imersão no evidenciador de placa (grupo teste) ou imersão em água deionizada (grupo controle). Os grupos teste foram imersos em 10 ml do evidenciador de placa Plax Magic (Colgate-Palmolive, São Bernardo do Campo, SP, Brasil) por 60 s três vezes por dia durante 35 dias, de acordo com a orientações de uso do fabricante. As leituras de cor foram feitas após 24 h da preparação dos espécimes e após 7, 14, 21 e 35 dias de imersão. Os resultados mostraram que o evidenciador de placa Plax Magic promoveu alteração de cor em todos os materiais usados e em todos os tempos de leitura. A alteração de cor foi maior na resina Charisma, seguida da Z250 e EvoluX. Portanto, o evidenciador de placa promove alteração de cor em todos os materiais testados. A resina composta Charisma demonstrou menor estabilidade de cor que as resinas Z250 e EvoluX, que, por sua vez, foi a mais estável. Palavras-chave: Resinas Compostas. Higiene Oral. Cor.

Resumen

Dental polymer-based luting materials are classified into esthetic resin cement, adhesive resin cement and self-adhesive resin cement. Due to the different component of each type of resin cement, the preconditioning method of tooth surface and the steps are different from each type of resin cement. The pre-treatment of adherend (ceramic, resin and metal) surface also varies with the type of resin cement and the manufacturer. In this study, the characteristics of each type of resin cement, mechanical properties, indication and advantages were investigated. Through these, clinical tips on using resin cements were suggested.

Resumen

Palm kernel shells have a high mechanical strength and good insulation strength. From these results it can be concluded that breakdown voltage of epoxy resin/palm kernel shells is higher than pure resin or resin/alumina. The highest breakdown voltage that occurred in the resin/palm kernel shells (8 wt%) is 76 kV. While the highest breakdown voltage that occurred in the epoxy resin/alumina (17 wt%) is 57.15 kV. Breakdown voltages of both samples are higher than the pure epoxy resin of 36 kV. The maximum electric field density (Emax) in the pure resin is 0.24 MV/cm that is lower than the resin/palm kernel shell (8 wt%) of 0.51 MV/cm and the resin/alumina (17 wt%) of 0.38 MV/cm. Discharge current has a lot of pulses and high amplitude when all solid insulation approached the breakdown event. However, the current pulses in the pure resin are higher than in both resin/palm kernel shell and resin/alumina. The epoxy resin mixture with palm kernel shells can be used as a new solid insulator.

Resumen

The uniqueness of alkyd resin, epoxy resin, and polyurethane nanocomposites has brought prominent recognition to the field of heavy-duty coating materials. This is expected due to the collaborative features of nano-sized materials such as the high surface area to volume ratio, great functionality per-unit space, extremely small sizes with high density, and that of alkyd resin, epoxy resin, and polyurethane (biodegradability, great gloss retention, adaptability, flexibility, durability, good drying properties, and weathering resistance). The objective of this review was to analyze the extent and currency of research and the development of alkyd, epoxy, and polyurethane nanocomposites in coating applications. Some of the several types of modifications discussed in this review are the incorporation of varying types of nanoclay and metal nanoparticles materials into alkyd resins, the incorporation of carbon nanotubes, MGel-graphene oxide (GO)/gelatin (MGel), Ni (II) Complex-Zeolite and starch-modified nano-ZnO into epoxy resin and the incorporation of (Rb2Co(H2P2O7)2.2H2O), modified nanoparticles of ZnO, diminished graphene oxide (dGO) into polyurethane and their effects on coating applications. The various studied modifications resulted in nanocomposite end-products with much improved properties. However, there are several challenges to the development of nanocomposites that need urgent attention. Some of the challenges discussed are the difficulty involved in transforming fabricated nanocomposites from laboratory to commercialized scale, the capital-intensive nature of synthesizing large nanopowder, etc.
