ABSTRACT:
Disclosed is an epoxy resin curative exhibiting extended pot life, increased resistance to heat and chemicals, lower reactivity at ambient temperatures and increased reactivity at moderately elevated temperatures which comprises from 1 to 5 parts by weight of 1-isopropyl-2-methyl imidazole per 100 parts by weight epoxy resin. The latent reactive properties make the curative potentially useful in a variety of applications.
