Polytek PlatSil® 73-45 Silicone Rubber
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber
Material Notes:	Description: PlatSil® 71 & 73-Series Silicone Rubbers are twocomponent, room temperature curing (RTV) systems that cure to flexible, high-strength rubbers. These platinum-cured (or additioncured) systems can be used to make flexible molds or parts that offer excellent release properties, good chemical resistance, and high dimensional stability. PlatSil® molds offer long library life and are a good choice for casting resin (polyurethane, polyester, epoxy), polyurethane rubber and foam, wax, plaster and concrete. Polytek offers additives to vary viscosity and cure time of the liquid rubber, as well as hardness and color of the cured rubber. Product Line Features: Two-part, platinum-cured (addition-cured) silicone rubbers Room temperature curing (RTV) Range of hardness from A10 to A60 Reproduces fine details Low shrinkage upon cure; high dimensional stability Release agents not required for casting many materials in PlatSil® molds Cured molds have long library life Thicken with liquid thickener for brush-on application Information provided by Polytek
