Features Of DOWSIL 832 Multi-Surface Silicone Adhesive

  1. Acetoxy-cure silicone formulation delivering fast skin-over and excellent adhesion to diverse substrates without primer.

  2. Exceptional resistance to weathering, UV exposure, and extreme temperatures (–40 °C to +150 °C continuous).

  3. Low modulus elasticity provides high movement capability (±25% joint movement) and long-term sealant integrity.

  4. Non-corrosive to metals and safe for use on sensitive surfaces including anodized aluminum and coated glass.

  5. Meets ASTM C920 Type S, Grade NS, Class 25, T1, M, O, G, and UL 94 HB flammability requirements.

Typical Applications Of DOWSIL 832 Multi-Surface Silicone Adhesive

  1. Perimeter sealing of insulated glass units (IGUs) in commercial fenestration systems.

  2. Adhesive and sealant for architectural aluminum curtain walls and metal composite panels.

  3. Joint sealing in precast concrete façades and structural glazing assemblies.

  4. Weatherproof bonding of signage substrates, including acrylic, polycarbonate, and stainless steel.

  5. Interior/exterior trim and molding attachment in transportation and modular building applications.
