- Cure
SG4528-040CU-103V is designed to cure between 250o F and 350o F. Cure at 250o F takes place in one hour at 250o F, however, cure times and temperatures can be extended to 90 minutes and post cures at 350o F to achieve a higher Tg. Alternatively, a processing profile of 60-90 minutes at 350o F can be used to affect a cure.
