Amine-modified epoxy resin reacted in presence of latent hardener

摘要

A method for making a one-component epoxy resin system comprises reacting (A) an epoxy resin and (B) an amine solidifying system present in insufficient quantities to cause gelation in the presence of a latent hardener (C) and an expanding agent (E), each of which remains unreacted under the reaction conditions for (A) and (B), to yield a product with a Kofler Heat Bank melting point of less than 55° C. and a melting point stability of at least six months at normal workshop temperatures.
