CURING AGENT FOR EPOXY RESIN

摘要

PROBLEM TO BE SOLVED: To obtain a reaction product for a latent epoxy curing agent, having a higher stability against mechanical stress and an improved pot life by using a reaction product of a microgel having specified groups with a nitrogenous base. SOLUTION: This is a reaction product of a microgel containing carboxylic groups with a nitrogenous base. It is desirably one in which the microgel is a copolymer of at least one unsaturated carboxylic acid with at least one polyfunctional crosslinking agent. It is more desirably one in which the microgel is a copolymer of at least one unsaturated carboxylic acid with at least one carboxyl-free vinyl monomer and at least one polyfunctional crosslinking agent.
