Medium Modulus Dow Corning 991 Silicone High Performance Sealant








2 Feature
Dow Corning 991 Silicone High Performance Sealant is a medium modulus one part, elastomeric sealant specifically designed for weatherproofing sensitive natural stone, glass and metal panels where aesthetic considerations are important. It cures to a flexible elastomer on exposure to atmospheric moisture, producing a durable, weather resistant seal with the ability to form strong bonds with most building materials. Because of its medium modulus and good adhesion, it provides excellent weatherproofing performance in dynamically moving building joints.
