View Full Version : Need tips for applying Epoxy to Silicone Rubber mold

This is my first post here, I'm not too sure were I should be asking this question.

I need some help/advice on a project I'm working on.

I made a silicone rubber mold and what I need to do now is apply epoxy resin (with hardener) to the silicone rubber so I can have a negative (shell). But i'm concerned that the epoxy resin will stick to the silicone rubber and I will be unable to remove it after .

What do I need to do so this doesn't happen ?

If you used one of the standard silicones the epoxy shouldn't stick- however a litle mold release couldn't hurt. there are many out there for this purpose but in a pinch Pam cooking spray will work
