CURATIVE

A coating created entirely from plant-derived ingredients is disclosed. Illustrative embodiments of the coating may be particularly well suited for use on leather-like materials created from epoxidized natural rubber-based formulations. Illustrative embodiments of the coating created may be comprised of substantially the reaction product between epoxidized vegetable oil and a polyfunctional naturally occurring acid (such as citric acid). Illustrative embodiments this reaction product may be used to produce porosity-free castable resins and vulcanize rubber formulations based on epoxidized natural rubber. Materials made from disclosed materials may be advantageously used as leather substitutes.

Curative and method

A thermoset material containing -hydroxyesters wherein said thermoset material is subject to a mechano-chemical process to regenerate an epoxide and a carboxylic acid functionality. A curative for epoxidized plant-based oils and epoxidized natural rubber is created from the reaction between a naturally occurring polyfunctional acid and an epoxidized plant-based oil is disclosed. The curative may be used to produce porosity-free castable resins and vulcanize rubber formulations based on epoxidized natural rubber. Materials made from disclosed materials may be advantageously used as leather substitutes.
