ABSTRACT:
Latent catalysts for epoxy reactions are prepared by reacting a tetrasubstituted onium compound such as tetrabutylphosphonium acetate acetic acid complex with an acid or metal salt of an acid having a weak-nucleophilic anion such as fluoboric acid. These catalysts provide stable latent catalysts for epoxy resins for advancement or curing reactions.
