PolyCoat Sealer & Release Agent

PolyCoat is a one-part moisture-curable silicone sealant which can be sprayed or brushed to seal porous models before applying liquid rubber. One to three coats can typically be applied to seal masters of varying levels of porosity, surface texture and detail. In many cases, PolyCoat serves as both the sealer and release eliminating the need for further release application when using liquid polyurethane mold rubbers. PolyCoat can be applied to rigid masters as well as to cured rubber molds to provide semi-permanent release and mold longevity.
