NONWOVEN CLOTH FOR LAMINATE BOARD

摘要

PROBLEM TO BE SOLVED: To provide a nonwoven cloth for a laminated board useful for a print circuit board, an insulation board or the like requiring thermal resistance to soldering. SOLUTION: The nonwoven cloth for a laminated board comprises a fiber and a binder resin binding the fibers together where the binder resin comprises a main component which comprises o-cresol novolac type epoxy and a curing agent resin and a high molecular weight epoxypolyol resin having 1,000 to 100,000 molecular weight. The epoxypolyol resin is produced by introducing a reactive group with a glycidyl group, and the curing agent is a compound containing an active hydrogen.
