Features Of Dow DOWSIL Q2-7566 Adhesive

  1. High-performance, one-component, addition-cure silicone adhesive with excellent adhesion to low-surface-energy substrates including plastics and coated metals.

  2. Fast room-temperature tack-up and rapid cure upon heat activation (e.g., 100 °C for 5–10 minutes), enabling high-throughput manufacturing.

  3. Outstanding thermal stability across –55 °C to +200 °C continuous service range, with short-term resistance up to 250 °C.

  4. Low modulus and high elongation (>150%), providing superior stress relief and vibration damping in dynamic assemblies.

  5. UL 94 V-0 rated for flame retardancy and compliant with RoHS and REACH directives for electronics and automotive applications.

Typical Applications Of Dow DOWSIL Q2-7566 Adhesive

  1. Automotive LED headlamp and taillamp assembly, including lens-to-housing bonding.

  2. Electronics encapsulation and structural bonding of sensors, power modules, and battery management systems.

  3. Medical device assembly requiring biocompatibility support (ISO 10993-5 cytotoxicity tested) and cleanroom-compatible processing.

  4. Industrial lighting fixtures where thermal cycling resistance and optical clarity retention are critical.
