Is room cured epoxy (without post curing) stronger and more warp resistant than VER?
Is Johnny from the USA larger than Kenny from England?
Very difficult to tell. These questions are too general to give a proper answer.
VER has a bit of shrinkage, but not much more than epoxy.
Postcuring helps removing the brittleness of some epoxies, but there are others that are not brittle at RT cure.
You kill me sometimes herman!! The real query , is Pat from England prettier than Pat from New Jersey,lol. -(thinking of Saturday Night Live’s character PAT, a he/she or unisex character.)
I often read that many VER’s are a modified Epoxy. I guess the short answer is ALL resin systems can benefit from a room cure followed by a post tg cure.
