Wood finishes from modified coconut coir dust extract

Describes experiments with the use of coconut coir dust extract as a raw material in the production of polyurethane and epoxy resin wood finishes, using benzoylated and methylated derivatives of the extract modified with isocyanates to produce polyurethane resins, or with epichlorohydrin to give epoxy resins, and using the copolymer resins formed in the formulation of wood finishes. Finds that the incorporation of cashew nut shell liquid into the copolymer resins further enhances the film‐forming properties of the finishes.
