Dowsil™ Adhesives/Sealants

For more than 70 years, Dowsil™ silicon-based sealants provide a range of effective, economical solutions for specified and general-purpose applications. They last longer and are more versatile than most organic polymer sealants.

Benefits of DOWSIL

 Long term flexibility and stability over a wide temperature range
• Weather and moisture resistance
• Chemical stability
• Good adhesion and bond strength
• Good electrical properties
• Low flammability

Why Silicones?

  • Protection that typically lasts three times longer than organic materials in
    the same applications, thus avoiding premature and costly renovations
  • Proven performance with successful track records in a range of diverse
    applications
  • Outstanding life-cycle value
  • All-weather application and performance, with resistance to UV exposure,
    ozone, rain, snow and extreme temperatures
  • More durability than organic-based materials
  • Continued flexibility and adhesion, even while being stretched or
    compressed
  • Resistance to cracking, splits or tears without hardening or fading
  • Easy application over a wide temperature range Organics are prone to
    chemical reversion, a phenomenon in which organic polyurethane loses its
    cured properties and reverts to a substance with the softness of chewing
    gum. The differences between silicones and organics are the difference
    between long-term value and premature failure. Silicones prevail.

One-Part Moisture Cure (RTV)

These silicone polymers work with a condensation reaction in humidity at typical room conditions, but the cure can be accelerated by increasing temperature and humidity. RTV sealants are easy to install, and they offer relatively low cost and good adhesion.
