Silicone Sealant Performance — at Urethane-Competitive Prices
Need an economical solution for your small- to mid-size projects, without compromising performance? You can’t get better protection for the price than with DOWSIL™ Contractors Concrete Sealant (CCS) and DOWSIL™ Contractors Weatherproofing Sealant (CWS). Unlike organic urethane products, these durable silicone sealants:
- Are virtually unaffected by UV light, ozone, rain, snow or temperature extremes
- Stay flexible and maintain adhesion, even while being stretched or compressed over time
- Will not crack, split or tear
Plus, unlike many urethane or acrylic products with no published warranty, CWS and CCS carry the 5-Year Weatherseal Limited Warranty from Dow Consumer Solutions, a trusted business that stands behind its claims.
3X Longer Life = Lower Ownership Costs
Dow Consumer Solutions brand silicone construction sealants significantly outperform competitive urethane sealants—lasting up to three times longer to dramatically lower maintenance and lifetime ownership costs while helping keep your ROI on track.
Paintable urethanes break down under movement and UV exposure. But with 100% silicone CWS and CCS, you get a wide range of standard, catalog and custom color offerings with our Color It Right program for long-lasting color that keeps you looking good.
Ideal for small- and mid-size projects, CWS and CCS provide all-temperature gunability and performance, and primerless adhesion to many common porous and non-porous building substrates.
