PolyCoat

PolyCoat is a sealer and semi permanent release that can be sprayed or wiped onto polyurethane rubbers to give them a thin silicone coating that reacts and bonds to the underlying polyurethane surface. This thin coating can do amazing things.

For Mold Making: Apply PolyCoat to porous (may require multiple coats depending on porosity) or non-porous models when making polyurethane and platinum-cured silicone rubber molds (not recommended for use with liquid tin-cured silicone rubber). Since PolyCoat leaves a dry, cured silicone coating on a surface, it may be used without additional release agent. This can be quite advantageous when making a polyurethane rubber mold as no residual release will transfer to the cured mold surface from the mold making process.
