Chemical Concepts Chem-Set™ RTV 6500 Silicone (Red)
Categories: Polymer; Adhesive; Thermoset; Silicone; Silicone, RTV, Adhesive/Sealant Grade

Material Notes: Chem-set™ RTV 6500 Silicone Heat Resistant Sealant is a one-part, nonslumping paste that cures to a rubbery solid at room temperature on exposure to water vapor in the air. This silicone product is formulated to perform at temperatures ranging from -65 to 260º (-85 to 500ºF) for continuous operation and to 315ºC (600ºF) for intermittent exposure. It can be used for numerous sealing and bonding applications. Non-slumping sealant designed for sealing and bonding applications exposed to temperatures as high as 315°C (600°F).

APPLICATIONS: The high temperature properties of this sealant make it ideally suited for: Sealing and encapsulating heating elements in appliances, Aerospace gasketing, Moving oven belts, Industrial ovens, Bag filters on smoke stacks, Other critical bonding, sealing, potting, encapsulating and protective coatings, where parts must perform at high temperatures.
