“…The polyol-poly(ricinoleic acid) polyesters possessed melting points below -7 7C and high viscosity and viscosity indices (155 for the pentaerythritol tetraester), suggesting their potential use as biodegradable lubricant materials. Moreover, castor oil was used in combination with a PA system in the preparation of coating adhesives, and some of these formulations showed excellent adhesion properties, satisfactory flexibility and good resistance to several chemicals [181]. Epoxidized castor oil was blended with PMMA in 80 : 20, 60 : 40 and 20 : 80 weight ratios, but these mixtures showed a certain degree of incompatibility [182,183].…”

Castor oil is, as many other plant oils, a very valuable renewable resource for the chemical industry. This review article provides an overview on this specialty oil, covering its production and properties. More importantly, the preparation, properties and major application possibilities of chemical derivatives of castor oil are highlighted. Our discussion focuses on application possibilities of castor oil and its derivatives for the synthesis of renewable monomers and polymers. An overview of recent developments in this field is provided and selected examples are discussed in detail, including the preparation and characterization of castor oil-derived polyurethanes, polyesters and polyamides.

“…This communication will review the performance of these castor oil‐modified epoxy and polyamide resin surface coatings and adhesives. Based on the results of this study, it has been found that these systems offer some advantages without significantly compromising the traditional properties of epoxy and polyamide resin in a variety of applications (Shukla et al , 2005).…”

“…Polyurethane resin can also be used for epoxy adhesive system, which show promise as high strength structural adhesive. Epoxy phenolic resin is also a modified form of epoxy resin, which can be prepared by epoxidation of phenol novolac, cresol novolac resin and provides higher functionality for better adhesion and chemical resistance (Shukla et al , 2005).…”

PurposeTo reduce the cost of epoxy adhesive without affecting the properties of epoxy adhesive in two pack system.Design/methodology/approachFor effective toughening, adhesion, chemical resistance, etc. various compositions were made by incorporating flow modified solid epoxy resin. The impact, adhesive strengths and some other properties of the unmodified and modified epoxy networks were characterised.FindingsThe modification of epoxy resin using flow modified solid epoxy resin showed significant enhancement of impact and adhesive strengths and chemical resistance over the unmodified one. The optimum results were obtained at 13.66 parts per hundred parts of epoxy resin (phr) of modifier by replacing 4.33 phr of aerosil.Research limitations/implicationsThe modifier, 7004 FM, used in the present context was high molecular weight flow modified epoxy resin. Besides, these results could be obtained from other grades of flow modified high molecular weight epoxy resin. In addition, the efficiency of modification of epoxy resin using this could also be studied.Practical implicationsThe method developed provided a simple and practical solution to removing the costly aerosil without affecting properties such as toughness, adhesive strength and chemical resistance of the cured epoxy.Originality/valueThe method for enhancing toughness, adhesive strength and chemical resistance of cured epoxy was novel and could find numerous applications in surface coating and adhesive.

“…The use of this vegetable oil is vastly explored in the ERs fields since their use can increase the flexibility of the resins, alongside their biocharacter. For instance, Shukla and co-workers [29] reported the use of CO to improve the flexibility and toughness of the final materials, which can be used in coating and/or adhesive applications. Patel et al [30] used CO without further modification to react directly with DGEBA, obtaining castor oil-epoxy resin products (COERs).…”

The urgent need to replace fossil resource-based products is considerably increasing in the past few years, resulting in the search for more sustainable materials, with the aim of reducing the wastes from polymer pollution, solving economic and environmental issues. This is even more relevant in industrial fields, where toxic compounds are the basis of their polymeric formulations. Herein is reported the most relevant advances of epoxy resins (ERs) in the past decade, with great emphasis on the replacement of bisphenol A (BPA), leading to the production of renewable-based ERs with good properties. The synthesis of ERs based on renewable sources, such as vegetable oils, phenolic compounds, sugars and the outcome in the material's structure is explored within this review. Emphasis is also given to the use of new biobased curing agents and biofillers to enhance the biocharacter of the ERs.
