Brand Name: DOWSIL™ 736 Heat Resistant Sealant
Package Size: Available in 90 mL tubes, 300 mL cartridges, 17.7 kg pails, and 205 kg drums.
Shelf Life: 30 months from the date of manufacture.
DOWSIL™ 736 Heat Resistant Sealant is a one-part, non-slumping silicone paste that cures to a rubbery solid upon exposure to atmospheric moisture at room temperature. It is specifically formulated to withstand continuous exposure to temperatures ranging from -65°C to 260°C (-85°F to 500°F) and intermittent exposure up to 315°C (600°F). This makes it ideal for high-temperature sealing and bonding applications.
