Abstract
PURPOSE: The titled composition, prepared by incorporating a polycarboxylic acid anhydride and an epoxy resin with a specific urethane-modified diester dicarboxylic acid as a curing agent, capable of giving a transparent cured article having improved flexibility, water resistance and alkali resistance, and suitable for coating, etc.
CONSTITUTION: An epoxy resin composition, prepared by incorporating (A) a urethane-modified diester dicarboxylic acid, having two terminal carboxyl groups, and obtained by reacting a dibasic acid, e.g. maleic acid, or an acid anhydride polycaprolactone, with a dihydric alcohol, e.g. and a diisocyanate, e.g. tolylene diisocyanate, with (B) a polycarboxylic acid anhydride, and (C) an epoxy resin at a weight ratio between the components (A) and (B) of preferably (5/95)W(40/60). The total amount of the components (A) and (B) is 0.85W1.2 equivalents based on one equivalent component (C).
USE: Coating with a thin film thickness, casting or embedding electrical parts.
