DOWSIL™ 736 Heat Resistant Sealant

  • 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.

 

Applications:

  • 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
