Silicone Construction Sealants by DOWSIL™

First introduced in 1977, DOWSIL silicone Building Sealants have long been the industry’s choice for sealing glass and metal in structural glazing applications, as well as weatherproofing. In addition, these high performance, engineered silicone sealants are popular for perimeter sealing, weatherproofing and well suited for a variety of other applications. DOWSIL offers silicone construction sealants specially formulated for stone curtainwall, and masonry construction including in expansion and control joints, pre-cast concrete panel joints, and curtainwall and mullion joints as well. These silicone sealants are virtually unaffected by sunlight, ozone, rain, snow or temperature extremes. They stay flexible and maintain adhesion even while being stretched or compressed. They won’t chalk, crack or split. And, when properly installed, they have a life expectancy of 20 years or more of leak-free service.

Silicone Glazing and IG Sealants by DOWSIL

These high performance silicone glazing sealants combine the best performance characteristics of both DOWSIL’s high and low modulus building sealants that demonstrate: unprimed adhesion to most common construction materials; a physical property profile that is strong enough for structural and non-structural glazing with sufficient movement capability for most weatherproofing applications; excellent fire-resistant properties; long cure times for easy, convenient tooling; a non-corrosive by-product; a low odor while curing; and excellent weathering, durability and recovery after extension and compression. DOWSIL silicone insulating glass (IG) sealants come in one and two part formulas that exhibit excellent unprimed adhesion to uncoated glass, aluminum and galvanized steel, consistently non-slumping which permits automated glazing, excellent shelf life and easy tooling.
