DOWSIL MS-1002 Moldable Silicone Adhesive

DOWSIL MS-1002 is a moldable silicone adhesive from Dow’s DOWSIL MS series—offering instant tack, excellent adhesion to diverse substrates, and room-temperature curing without shrinking or cracking. It remains flexible after cure, resists moisture/UV, and enables easy hand-forming for prototyping, sealing, and custom gasketing applications.

Features Of DOWSIL MS-1002 Moldable Silicone Adhesive

  1. Room-temperature vulcanizing (RTV) silicone with exceptional moldability and hand-formability prior to cure.

  2. Excellent adhesion to a wide range of substrates including metals, plastics, glass, and ceramics without primer.

  3. High elasticity and permanent flexibility after full cure—resists cracking, shrinking, or embrittlement over time.

  4. Good resistance to moisture, ozone, UV radiation, and extreme temperatures (–55 °C to +200 °C continuous).

  5. Low volatility and non-corrosive formulation—meets ISO 10993 biocompatibility screening requirements for incidental contact.

Typical Applications Of DOWSIL MS-1002 Moldable Silicone Adhesive

  1. Sealing and gasketing of electronic enclosures and automotive sensor housings.

  2. Hand-applied potting and strain relief for wire harnesses and PCB assemblies.

  3. Fabrication of custom-shaped thermal interface pads and vibration-damping mounts.

  4. Repair and refurbishment of HVAC components, lighting fixtures, and industrial control panels.

  5. Prototyping and low-volume production of silicone-based functional parts requiring rapid manual shaping.
