Data Sheet
SDS
Thurmalox 2655 is a one-part, room temperature vulcanizing (RTV) silicone adhesive/sealant for high-temperature industrial applications. It cures to a tough, elastomeric rubber upon exposure to atmospheric moisture and retains permanent flexibility from -80ºF to 550ºF (-62ºC-288ºC) and will withstand intermittent exposures to 650ºF (343ºC).
Thurmalox 2655 Adhesive/Sealant provides excellent adhesion to most surfaces including: metals, painted surfaces, ceramics, glass, rubber and plastics.
