Abstract

PURPOSE: The titled composition excellent in blistering resistance, high-temperature water resistance and peeling strength, comprising a rubber-modified epoxy resin and finely divided dicyandiamide.
CONSTITUTION: 97W50wt% epoxy resin having at least two epoxy groups in the molecule, epoxy equivalent weight 100W3,500, is reacted with 3W50wt% carboxyl group-containing rubbery polymer having at least 1.5W2.5 (on an average) carboxyl groups in the molecule, MW 1,000W5,000, e.g., butadiene/acrylonitrile copolymer, at 70W160°C for 0.5W4hr to obtain a rubber-modified epoxy resin, epoxy equivalent weight 200W5,000. Next, 100pts.wt. said resin is mixed with 2W 20pts.wt. finely divided dicyandiamide, particles with 5μ or smaller diameters ≥90wt% and 0W5pts.wt. silane coupling agent, e.g., vinyltriacetoxysilane.
