Polytek PolyCoat Sealer/Release for Rubber Mold Making
- PolyCoat is one-part moisture-curable silicone sealant which can be sprayed or brushed to seal porous models before applying liquid rubber.
- 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.
- PolyCoat should be used to seal a surface such as wood, tile, stone, concrete, plaster, etc. before creating a rubber mold.
- PolyCoat can also be used to create a semi-permanent 'release' on a master polyurethane mold that will have repeated molds made from it, and won't need Pol-Ease 2300 Release applied each time. Polyurethane Rubber molds treated with PolyCoat imitate Silicone Rubber molds.
- Do Not use pour liquid Silicone Rubber on surfaces treated with PolyCoat.
- Sold in Quart (1.5 lbs), and Gallon (8 lbs) sizes.
- Brush or spray 1 to 3 thin coats of PolyCoat on surface.
- Allow to dry 10 minutes between coats.
- Let final coat dry 30 minutes in warm area or under heat lamp.
