Features Of Dow DOWSIL 1437 Industrial Sealant and Adhesive

  1. High-performance silicone-based formulation offering excellent adhesion to metals, plastics, glass, and painted surfaces.

  2. Wide service temperature range from –40 °C to +200 °C for reliable performance in demanding industrial environments.

  3. Low modulus elasticity provides superior resistance to thermal cycling and mechanical vibration without cracking or debonding.

  4. Non-corrosive and acetoxy-cure free—safe for use with sensitive electronic components and non-reactive with most substrates.

  5. Good resistance to weathering, UV exposure, and ozone, ensuring long-term durability in outdoor applications.

Typical Applications Of Dow DOWSIL 1437 Industrial Sealant and Adhesive

  1. Sealing and bonding of HVAC enclosures and ductwork assemblies.

  2. Attachment of nameplates, trim, and decorative panels on industrial equipment and transportation vehicles.

  3. Mounting and sealing of sensors, control housings, and electrical junction boxes.

  4. Gap-filling and vibration-damping in machinery frames and structural metal components.

  5. General-purpose industrial assembly where flexibility, thermal stability, and substrate compatibility are critical.
