Electronics Adhesives and Sealants

Dow’s next-generation silicone-based adhesives and sealants

From shielding heavy machinery from harsh outdoor environments to protecting sensitive electronic circuitry from mechanical stress, to ensuring a secure foundation for subcomponents and larger assemblies to strengthening bonds between lighter-weight materials, our next-generation silicone-based adhesives and sealants offer numerous advantages. With reliable performance over operating temperatures ranging from -45C to 275C, our proven portfolio of non-corrosive sealants and adhesives are available in a number of viscosities and cure chemistries.

Taking the stress out of bonding and adhesion

Whatever your desired outcome, adhesives and sealants play a pivotal role in protecting electronics, advanced assembly and lighting components from environmental stress and moisture in even the most demanding applications. Below are just a few of the benefits.

Accelerated Heat Cure Adhesives

Offering greater control and processing flexibility, standard grades enable adhesion in as few as 20 to 30 minutes at ambient temperatures of 150C, while high-performance grades can cure within minutes at the same temperature.

Hot-Melt Silicone Adhesives

Providing primerless adhesion to glass, plastics, metals and many other substrates, these adhesives can be applied as a liquid melt but cool to a solid and form a viscoelastic material with enhanced physical properties when they react with ambient moisture.

One-Part Moisture-Cure (RTV) Silicones

Requiring no mixing or oven equipment to process, these vulcanizing adhesives draw moisture from ambient air to cure simply and cost-effectively at room temperature. The cure can be accelerated by increasing temperature and humidity.

Silicone Foams

Cost-effective alternatives to preformed gaskets and foam tapes when sealing high-tolerance gaps, these foams help reduce waste and expedite production while protecting against ambient air, moisture, dust, vapor, vibration, heat and more.
