Features Of Dow DOWSIL 7388 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 humidity over extended service life.

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

  4. Non-corrosive cure chemistry — acetoxy-free — making it safe for use with sensitive electronic components and copper-containing materials.

  5. Good flow and gap-filling capability with moderate tack time, enabling reliable manual or automated dispensing.

Typical Applications Of Dow DOWSIL 7388 Silicone Adhesive

  1. Automotive lighting assembly — bonding polycarbonate lenses to metal or plastic housings.

  2. Electronic device encapsulation and gasketing — sealing sensors, LED modules, and control units.

  3. Architectural glazing and façade systems — structural and non-structural bonding of glass, aluminum, and composites.

  4. Industrial appliance manufacturing — durable bonding of control panels, displays, and trim components.

  5. Medical device assembly — biocompatibility-supporting bonding where ISO 10993-compliant materials are required (subject to validation).
