ABSTRACT:
This invention relates to an improved method for curing polyepoxide resins at elevated temperature and particularly to a method for reducing the time required to effect cure of thermosetting resins at elevated temperature without sacrificing performance. In the basic process, an epoxide resin comprising a polyglycidyl ether of a polyhydric phenol is mixed with cycloaliphatic amine, e.g., di(4-aminocyclohexyl)methane, di(4-amino-3-methylcyclohexyl)methane, and isophoronediamine in an amount sufficient to effect cure of the polyepoxide resin at an initial temperature and then raised to a final cure temperature. The improvement for reducing the time necessary for cure comprises:
