Abstract
Compounds with a plurality of oxirane functional groups can be cured to a fixture in less than one minute with a catalyst composition of a trityl or tropylium salt of a non-nucleophillic anion and a suitable solvent. Typical catalyst salts include trityl tetrafluoroborate, trityl hexachloroantimonate and tropylium hexafluorophosphate. The catalyst composition may conveniently be extended with liquid polymeric vehicles and acidic fillers.
