Features Of Dow DOWSIL 832 Multi-Surface Adhesive Sealant

  1. Room-temperature curing silicone sealant with excellent adhesion to glass, metal, ceramics, and most plastics without primer.

  2. Non-corrosive, neutral-cure formulation releases methanol during cure—safe for sensitive substrates including electronics and anodized aluminum.

  3. High elasticity and permanent flexibility retain sealing integrity across wide temperature ranges (−40 °C to +150 °C).

  4. Excellent resistance to UV, ozone, weathering, and aging—maintains performance in outdoor and demanding environments.

  5. Low modulus design accommodates joint movement up to ±25% without loss of adhesion or cohesion.

Typical Applications Of Dow DOWSIL 832 Multi-Surface Adhesive Sealant

  1. Sealing and bonding of architectural glazing systems—including structural and non-structural glass-to-metal joints.

  2. Automotive interior assembly: bonding trim, emblems, sensors, and electronic housings on painted or coated surfaces.

  3. Electronics enclosures: sealing housings, connectors, and control panels where low outgassing and non-corrosive cure are critical.

  4. Appliance manufacturing: sealing control panels, door gaskets, and decorative overlays on stainless steel, plastic, and coated substrates.

  5. Industrial equipment assembly: vibration-damping bonds and environmental seals for HVAC components, lighting fixtures, and medical devices.
