Abstract
A resin system includes 100 parts by weight of an epoxy resin, from about 1/2 to about 10 parts by weight of an imidazole curing agent, and, optionally, an elastomeric material such as a rubber. The resin system without the elastomer is particularly useful as the matrix of a composite material or a potting compound, and the resin system with the elastomer is particularly useful as an adhesive. The resin system is cured at a low temperature and exhibits essentially no dimensional instability upon curing, and then is preferably post-cured at a higher temperature. The post-cured resin system has a softening temperature substantially higher than the normal post-cure temperature and has good mechanical properties.
