Title: The Innovations of Robert L. Spencer
Introduction
Robert L. Spencer is a notable inventor based in Lyndhurst, OH (US). He has made significant contributions to the field of adhesive technologies, holding a total of 4 patents. His work focuses on developing advanced adhesive compositions that enhance performance and application efficiency.
Latest Patents
One of Spencer's latest patents is for primerless urethane adhesive compositions. This two-component urethane adhesive requires no primer or pretreatment of the substrate, offering superior paint adhesion and the ability to withstand high-temperature bake cycles without substantial losses in adhesion. The innovation lies in the use of high molecular weight polyols in the prepolymer component, which are the reaction products of grafting reactions of acrylonitrile onto polypropylene polyols.
Another significant patent involves in-mold coating with epoxy acrylate and OH or amide-containing monomers. This invention allows for fiberglass reinforced plastic to be in-mold coated using a free radical peroxide initiated thermosetting composition. The composition includes a polymerizable epoxy-based oligomer with multiple acrylate groups, copolymerizable ethylenically unsaturated monomers, and other conventional components. Remarkably, this thermosetting composition utilizes a very low or nil amount of adhesion agents, achieving better flow and good coverage at reduced coating weights.
