ANTIFRAYING BINDER FOR GLASS FIBER WOVEN CLOTH AND GLASS FIBER CLOTH USING THE SAME

摘要

PURPOSE:To provide an antifraying binder which has excellent antifraying effect at the cut edges of glass cloth without change in thickness at the coated parts and can be used in an aqueous system at an increased curing speed. CONSTITUTION:The antifraying binder comprises (A) a reaction product of an epoxy resin of 150 to 1,000 epoxy equivalents and 500 to 2,000 molecular weight and a hydroxyl group-containing amine, (B) a water borne isocyanate type curing agent and (C) a reaction-accelerating catalyst. The glass fiber cloth is obtained by applying the antifraying binder to both selvages in a certain width.
