Curable resin composition

摘要

A curable resin composition has a low viscosity, hence is easy to handle, before curing and, after curing, gives cured products having good tensile characteristics and, in addition, good chemical resistance and water resistance. This composition includes (A) an oxypropylene polymer having at least one silicon atom-containing group having a hydroxyl group or hydrolyzable group bound to the silicon atom and having an Mw/Mn ratio of up to than 1.6 and a number average molecular weight of at least 6,000, and (B) an epoxy resin.
