UV intensity, temperature and dark-curing effects in cationic photo-polymerization of a cycloaliphatic epoxy resin

摘要

Cationic photopolymerisation offers some interesting features including not suffering oxygen inhibition, low shrinkage, good adhesion, dark curing after photoinitiation and thermal post-cure. Cationic systems have also benefited from the relatively recent commercial availability of the diaryliodonium salts.
