Dow Corning® Contractors Concrete Sealant and Dow Corning® Contractors
Weatherproofing Sealant Are The Right Choice
Dow Corning now delivers silicone performance at urethane-competitive
prices. Dollar for dollar, you can’t get better performance for the price than
with Dow Corning® Contractors Concrete
Sealant (CCS) and Dow Corning® Contractors
Weatherproofing Sealant (CWS). Unlike organic urethane products, silicone
Are virtually unaffected by UV light, ozone, rain, snow or temperature
Stay flexible and maintain adhesion, even while being stretched or
Will not crack, split or tear.
CCS and CWS carry a 5-Year Weatherseal Limited Warranty from Dow
Corning, a brand you can trust from a company that stands behind its claims.
Many urethane products carry no published warranty. With CCS and CWS, you don’t
have to compromise performance for price.
The commonly accepted thinking about sealants is that although silicone
offers superior performance, urethane is paintable. But what about the
long-term aesthetics of painted urethane sealant? If the paint can’t match the
sealant’s movement, it will crack, peel and fall off. Aside from aesthetic
issues, this exposes the sealant underneath to damaging UV rays. UV exposure
isn’t a problem for silicone sealants.
But as this image show, urethane sealants quickly degrade when exposed to UV
radiation. These latent defects make callbacks more likely and reflect poorly
on the quality of your workmanship ... even if you had no control over which
sealant was specified.
After 100 days (2,400 hours) of UV exposure in accelerated weathering and heat stability tests, the urethane sealant deteriorates, while the silicone sealant remains untouched.
Encouraging the use of price-competitive, 100% silicone CCS and CWS instead
of urethane can benefit your reputation and your budget! With a virtually
unlimited palette of colors available, you don’t
have to compromise performance for paintability.

Method , an innovative procedure that makes it easy to use silicone
sealants on paintable surfaces.)
There’s a sudden drop in temperature and your crew is now left trying to
fill thousands of lineal feet of construction joints with urethane sealant
that’s difficult to extrude. If you’ve ever been in this position, you’ll
appreciate the all-temperature gunnability of silicone sealants. CCS and CWS
also offer primerless adhesion to many common porous and nonporous building
substrates. (See product specifications for Section 07 92 00 for Joint Sealants for
more information.) CCS and CWS can save you time, labor and money ... not to
mention a lot of frustration! With CCS and CWS, you don’t have to compromise
application flexibility for price.
