Features Of Dow DOWSIL 7268 Silicone Adhesive

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

  2. Offers outstanding resistance to thermal cycling, UV exposure, and weathering across a wide temperature range (–55 °C to 200 °C continuous).

  3. Low modulus formulation provides superior flexibility and stress relief for bonded assemblies subject to vibration or differential expansion.

  4. Non-corrosive cure chemistry—releases methanol instead of acetic acid—making it safe for sensitive electronic components and copper surfaces.

  5. Good flow and gap-filling capability with controlled tack-free time, enabling reliable automated dispensing in high-volume manufacturing.

Typical Applications Of Dow DOWSIL 7268 Silicone Adhesive

  1. Automotive lighting assemblies—including headlamp and taillamp bonding where optical clarity and long-term seal integrity are critical.

  2. Electronic encapsulation and potting of sensors, power modules, and LED drivers requiring dielectric stability and thermal management.

  3. Appliance manufacturing for gasketing and structural bonding of control panels, display housings, and HVAC components.

  4. Industrial equipment enclosures where resistance to humidity, condensation, and mechanical shock is essential.

  5. Medical device assembly involving biocompatible-material-adjacent bonding (ISO 10993-tested per request; not for implantation).
