Abstract
An epoxy composition which is an infusible, gelled, heat curable, epoxy functional reaction product formed by mixing together: PA1 (A) one or more epoxy resins or epoxy group containing compounds; PA1 (B) a hardener system which will react with (A) to give a gelled solid, but which does not cause complete curing of (A) under the reaction conditions chosen for reaction of (A) and (B) to give a gelled solid; and PA1 (C) an optional further hardener system for (A) and the reaction product of (A) and PA1 (B), which is different from (B), and which remains largely unreacted with (A) and PA1 (B) under said reaction conditions.
