The seal you trust

Whether you’re a professional contractor or a do-it-yourselfer with professional standards, you want the seal you trust: DOWSIL™ brand.

DOWSIL™ adhesives and sealants for professional and retail users are dependable, one-part silicone sealants with a history of proven performance. They are manufactured by Dow, a global leader in silicone sealant technology and innovation.

DOWSIL™ silicone sealants and adhesives benefits:

  • One-part ease of use; fast, no-mix application
  • Reliable adhesion to a variety of substrates
  • Outperform and outlast organic weatherproofing sealants
  • Greater UV stability, temperature and weather resistance than organic sealants
  • Are inherently waterproof
  • Remain flexible over a wide temperature range so are easy to apply in cold weather - will not become brittle, shrink, chalk or crack with age
  • Last longer and need to be replaced less often than many organic sealants, which reduces lifetime costs and contributes to sustainability
  • Room temperature vulcanizing (RTV), meaning they cure at room temperature

Key Features

  • Weatherproofing
  • Sealing, bonding and adhering
  • Enhancing building aesthetics
