Features Of DOW DOWSIL SE 9187 L Silicone Adhesive

  1. High-performance, one-component, moisture-curing silicone adhesive with excellent adhesion to low-surface-energy substrates.

  2. Offers outstanding resistance to thermal cycling, UV exposure, and weathering for long-term outdoor durability.

  3. Low modulus formulation provides superior flexibility and stress relief in bonded assemblies subjected to vibration or expansion/contraction.

  4. Non-corrosive and acetoxy-free — safe for use with sensitive metals, electronics, and coated surfaces.

  5. Good flow and self-leveling behavior enables consistent bead control and gap-filling capability up to 6 mm.

Typical Applications Of DOW DOWSIL SE 9187 L Silicone Adhesive

  1. Structural bonding of architectural glazing systems, including insulating glass (IG) units and curtain wall components.

  2. Sealing and bonding of solar photovoltaic modules and junction boxes exposed to harsh environmental conditions.

  3. Assembly of LED lighting fixtures requiring reliable thermal stability and optical clarity retention.

  4. Adhesion of automotive exterior trim, sensors, and lighting housings where flexibility and weather resistance are critical.
