ABSTRACT:
A curable composition which contains polyepoxide and amine curing agent free of amide groups and which is of a substantially lower viscosity than the polyepoxide is improved by thickening the amine to a viscosity comparable to that of the polyepoxide. The amine is thickened by either incorporating into the amine curing agent a polyamide in an amount not exceeding 35 percent by weight based on the amount of amine curing agent of a polyamide; or converting a portion of the amine curing agent to polyamide by in situ chain extension to form amide groups wherein the chain extension is carried out in an excess of amine curing agent before the amine curing agent is admixed with the polyepoxide component of the curable composition; or a combination thereof.
