Silpak R-3700-20 Translucent, Pourable Platinum Silicone System, Food Safe
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	Silpak R-3700-20 Liquid Silicone Rubber is a two-component, room temperature curing mold rubber. R-3700-20 silicone rubber is platinum activated, which, unlike tin-activated systems, do not shrink on cure or deteriorate over time. Molds made from R-3700-20 offer good chemical resistance, making them an appropriate choice when planning to cast polyesters, polyurethanes (plastic, foam, rubber), epoxies and more. It offers excellent release properties, making release agents unnecessary in many applications. Additives to vary the viscosity and cure time of the liquid rubber as well as hardness and color of the cured rubber are available. Features: Food Safe, Complies with 21CFR 177.2600 Low viscosity Easy release properties High Tear Strength Cures at room temp or accelerate with heat Easy Mix ratios Applications: This rubber system is used to make parts or molds used to cast the following: Polyester Epoxy Thermoplastics (polyvinyl) Urethane Any material where a release free casting is required Low melt metal (350°F) Wax Soap Plaster Information provided by Silpak a division of Polytek Development Corp.
