NuFlex® 302 High-Temperature Silicone Sealant is a medium modulus one-component acetoxy cure, non-sag caulking material. NuFlex® 302 High-Temperature Silicone Sealant cures to form a sturdy, rubbery solid upon exposure to moisture in the air.

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