Hi everybody,
I have the same problem with all EG160 moulds I prepared the last months: Taking the part out of the mould shows a perfect finish, but after postcuring in the recommended cycle there are points where it looks like air is trapped. But you could not see it before the curing process... any tips?

Regards and a wonderful christmas for everyone!

I too have had some problems with bubbles in EG160. Tried to degass but not sure if it‘s that effective as it is very thick in viscosity. Won‘t hurt though. Blowtorches or heatguns may help as well. Slower post curing ramps may also help. For me the backing paste used to be the biggest problem bubble wise, so take your time with that and work difficult areas first.
