URETHANE MODIFIED EPOXY ADHESIVE COMPOSITION

摘要

The present invention is comprised of an adhesive composition including an epoxy resin based on a polyglycidyl ether of a polyphenol and an urethane prepolymer having terminal isocyanate groups. The urethane prepolymer is reacted with hydroxyl groups of the epoxy resin so as to provide a multi-functional urethane modified epoxy resin having a functionality of four or more. Optionally, the epoxy resin can be acrylated.
