CHT ALPA-SIL 30201 Silicone Molding Rubber
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber
Material Notes:	Description: This is a pourable 2-part addition cure silicone elastomer system. After mixing parts ‘A’ and ‘B’ in the correct proportions, the system will cure at ambient temperatures within 24 hours, but the rate of cure can be accelerated by heat. The cured rubber exhibits excellent physical and electrical properties. Key Features Low viscosity, easily degassed Easy 1:1 mixing of the components High mechanical strength Suited for spray application Application: Due to its low viscosity and fast processing time the product is particularly suited for spray applications.
