Introduction

James R. Prom is a notable inventor based in Port Washington, WI (US). He has made significant contributions to the field of coatings and thermoset plastics, holding a total of 3 patents. His work focuses on developing advanced coating compositions and methods for producing coated molded articles.

Latest Patents

One of his latest patents is for Dual Cure Coating Compositions. These compositions are prepared using various techniques, including aminoplast crosslinking with residual hydroxy present on extended acrylated or UV cure polymers. Another method involves oxidative crosslinking of backbone drying oil unsaturation following UV cure. Additionally, UV chain extension can be employed via the reaction of pendent allylic groups with polymercaptans, followed by a melamine heat cure. The coatings are cured through UV exposure, followed by heating or air drying.

Another significant patent by Prom is a Method for Making Coated Molded Articles. This method produces coated, molded, fiber-reinforced thermoset plastic articles with an adherent coating in heated matched metal molds. The coating composition includes a polyurethane polyacrylate, which is a reaction product, substantially free of unreacted --NCO radicals, of an organic diisocyanate, a hydroxy alkyl acrylate or methacrylate, and an organic diol. The composition also contains initiators for addition polymerization and may include fillers such as inert particulate fillers, pigments, and mold release agents. The coating is applied in the matched metal mold after shaping the fiber-reinforced thermoset plastic article.
