Features Of DOWSIL TSSA Silicone Adhesive

  1. High-performance, one-component, moisture-curing silicone adhesive with excellent adhesion to glass, aluminum, and painted metal substrates.

  2. Low modulus formulation provides superior flexibility and stress relief for bonded assemblies subjected to thermal cycling or vibration.

  3. Excellent resistance to UV radiation, ozone, and extreme temperatures ranging from −40 °C to +150 °C long-term.

  4. Non-corrosive to sensitive metals and compatible with common automotive and architectural sealant primers.

  5. Meets ASTM C920 Type S, Grade NS, Class 25, use T (tensile) requirements for elastomeric sealants.

Typical Applications Of DOWSIL TSSA Silicone Adhesive

  1. Structural glazing in commercial curtain wall systems and storefronts.

  2. Bonding of insulated glass units (IGUs) to framing systems in architectural fenestration.

  3. Attachment of exterior cladding panels, including aluminum composite material (ACM) and fiber cement boards.

  4. Sealing and bonding in transportation applications such as bus, railcar, and specialty vehicle glazing assemblies.

  5. General-purpose bonding of non-porous substrates in industrial assembly and OEM fabrication.
