Hi just wanted to know mhat you use for release? I am dont resin infusion with epoxy resin with epoxy moulds. I use release wax the pva mould release. Is this the right way to do things? Thanks!
semi-permanent releases are the best. stay away from PVA, stuff is junk.
I wouldbt say that pva is junk. It does have its uses, in the right place and at the right time it can be very useful. It does however leave a funny textured surface on components that youwouldnt get with a very well waxed mould that didnt require pva.
So you guys saying use wax only?
I agree it does have its uses, however from a standpoint of production it doesnt make sense to use. Its good for pulling a one off something that has a poor surface. Using semi-permanents is the way to go.
What are semi-permanents?
they are liquid release agents that chemically bond to the mold surface. Frekote makes some good semi-permanent releases, just make sure get a sealer aswell as a release agent.
can I use wax on its own?
You can but be sure to get every square inch and put multiple coats down.
