ORGANIC VEGETABLE OIL BASED RESIN AND PREPARATION METHOD THEREOF

Disclosed are organic, UV resistant epoxy resins derived largely from vegetable oil based materials. More specifically, the present invention provides a virtually non-toxic, hypoallergenic UV resistant resin and method of producing and using the same that gives off substantially no VOCs and no disagreeable odors. The composition comprises a vegetable oil-based polyfunctional carboxylic acid, a cycloaliphatic anhydride, and an epoxy compound either of bicyclic difunctional epoxy resin, epoxidized vegetable oil or epoxidized polymer chains. The composition further comprises a catalyst and a wetting agent. In its cured state the material is leather like and exhibits high tensile strength as well as unusually high, totally reversible elongation. In an alternative embodiment, the resin comprises a cyclic anhydride (Lindride 16E). With increased amounts of cyclic anhydride, increased heat distortion temperature is exhibited; all while maintaining a high reversible elongation and high tensile strength In an additional alternative, an increased amount of Chromium III Octoate is used and in another alternative Phosphoric Acid.
