Features Of Dow DOWSIL SE 4422 Silicone Adhesive

  1. High-performance, one-component, moisture-curing silicone adhesive with excellent adhesion to diverse substrates including glass, aluminum, stainless steel, and painted surfaces.

  2. Offers superior resistance to thermal cycling, UV exposure, and weathering—maintaining integrity across -40 °C to +150 °C service temperatures.

  3. Low modulus formulation provides exceptional flexibility and stress relief in dynamic joints and assemblies subject to vibration or thermal expansion.

  4. Non-corrosive, acetoxy-cure chemistry ensures compatibility with sensitive electronic components and eliminates risk of metal corrosion.

  5. Easy-to-dispense thixotropic paste consistency enables precise application without sagging on vertical or overhead surfaces.

Typical Applications Of Dow DOWSIL SE 4422 Silicone Adhesive

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

  2. Sealing and bonding in automotive lighting modules, such as headlamp and taillamp housings.

  3. Electronic encapsulation and component mounting in power electronics, LED lighting fixtures, and control enclosures.

  4. Industrial assembly of HVAC components, solar panel frames, and appliance housings requiring durable, flexible adhesion.

  5. General-purpose bonding and sealing in transportation, marine, and building & construction applications exposed to harsh environments.
