expand as it hardens - reverse shrink epoxy
expand as it hardens - reverse shrink epoxy
(OP)
I'm doing some sand cast pattern making and I'm looking for something that I could pour over an existing part so that when it hardens it would expand instead of shink.
The reason is that when you cast aluminum it shrinks, about 1.3% therefore your patterns need to be that much bigger.
It follows that I'd need (ideally) something that would expand about that much.
Anything you guys can think of?
