Dow Corning CWS (Contractors Weatherproofing Sealant)


 

Dow Corning® Contractors Weatherproofing Sealant is primerless on most common nonporous building substrates. This unique weather resistant
formulation possesses a balanced adhesive strength, medium modulus, and high recovery, making it ideal to withstand adverse conditions
in common installations including moisture, movement, sheer, and deflection. It is easily gunnable in all weather conditions from -29 to 49°C
(-20 to 120°F). Because it requires no mixing and a smaller joint ratio, it is an economical, high-performance alternative to other sealant options with a ±40 percent movement capability.
