epdm nonfill from lube

[TechTerry]

we have a process that requires a mold release agent, but any moisture and we have a nonfill effect with the cured epdm. Any ideas on non liquid release agents or coatings?

Adding CaCO3 to the formula will provide mold relase. Stearic acid and waxes may help. If moisture is a problem add CaO. a solvent based mold lube would eliminate the water. It is almost impossible to answer without knowing the complete formula
