GEL COAT COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a gel coat composition that excels in adhesion to FRP produced using an epoxy resin as a matrix.SOLUTION: The gel coat composition according to the invention comprises a gel coat base resin and an aminosilane coupling agent and/or an epoxysilane coupling agent. A suitable silane coupling agent is a polymer type polyfunctional aminosilane coupling agent, and the gel coat composition comprising the same excels in adhesion to an epoxy resin in FRP, and can provide a molded article that does not compromise inherent physical properties of the gel coat composition.
