302 Hi-Temp Silicone

Technical Data Sheet

NuFlex® 302 Hi-Temperature (HT) Silicone Gasket Maker is a one-part, non-slumping 100% silicone sealant with the consistency similar to that of toothpaste. It cures when it is exposed to moisture in the air to form a tough rubbery seal.

NuFlex® 302 HT was formulated to perform at temperatures ranging from –65°C to 260°C (-85°F to 500°F) under continuous operating conditions. During intermittent exposure, NuFlex® 302 HT will withstand temperatures as high as 316°C (600°F). It is ideal for a number of sealing and bonding applications.
