PolyCoat Semi-Permanent Sealer and Release for Molds

Polytek PolyCoat Sealer/Release for Rubber Mold Making PolyCoat Sealer & Release Agent is a low-viscosity, semi-permanent sealer and release agent that leaves behind a thin coating of silicone. FOR INDUSTRIAL/PROFESSIONAL USE ONLY.  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. For Casting: PolyCoat can also be applied to aging PlatSil® and TinSil® Silicone Molds to improve performance (easier demolding) and extend their useful life. In addition, PolyCoat can be applied to firm polyurethane rubber molds to give
