Introduction of Polyester Resin Craft Molding Silicone---
Polyester Resin Craft Molding Silicone is a low viscosity, two-part condensation cure silicone rubber. It is used for mould making where it is mixed (with its catalyst) and then poured around a pattern to create a flexible silicone mould.
Polyester Resin Craft Molding Silicone has been specially selected for its ease of use, excellent performance and great value.
Once cured the silicone rubber is very soft and flexible making it perfect for casting complicated or intricate shapes where the cast part can be easily removed from the silicone mould.
