ABSTRACT:
Described are several preferred acid salts and complexes of N,N-dimethylpyridine (DMAP) and 4-(4-methyl-1-piperidinyl)pyridine (MPP) which are useful as curing agents or as accelerators in preferred epoxy resin curing processes. Also described are particularly preferred processes for forming cured epoxy resin materials which are advantageously employed in large production line scale operations, and curable coating compositions.
