Dow Corning introduces a new clean silicone building sealant that reduces the problems of substrate staining and residue run-down. Dow Corning® 756 SMS Building Sealant is formulated to reduce fluid migration, a common cause of staining of sensitive substrates like porous stone or masonry. Patent-pending surface-modified sealant (SMS) technology gives the cured sealant a low-friction surface that minimizes dirt pick-up, solving the problem of contaminants accumulating on the sealant and washing from the joint onto the substrate below, a particular challenge for glass and painted metal substrates.
MIDLAND, Michigan (PRWEB) December 18 2003-- Dow Corning introduces a new clean silicone building sealant that reduces the problems of substrate staining and residue run-down. Dow Corning® 756 SMS Building Sealant is formulated to reduce fluid migration, a common cause of staining of sensitive substrates like porous stone or masonry. Patent-pending surface-modified sealant (SMS) technology gives the cured sealant a low-friction surface that minimizes dirt pick-up, solving the problem of contaminants accumulating on the sealant and washing from the joint onto the substrate below, a particular challenge for glass and painted metal substrates.
In the past, building owners often had to choose between a clean sealant or a durable one. Some urethane sealants maintain a clean appearance by sloughing off the sealant surface, thinning the sealant bead and compromising weathersealing performance over the space of only five to seven years. Now the all-new SMS technology gives building owners both improved aesthetics and long-lasting performance in a single product. The sealant provides the long-life durability and flexibility inherent to silicones. In fact, Dow Corning, the world leader in silicone technology for the construction industry, offers 20-year weathersealing and non-staining warranties on Dow Corning 756 SMS Building Sealant.
Dow Corning 756 SMS Building Sealant is available in six standard colors and can be custom pigmented to match virtually any design requirement. Its unique matte finish also complements building aesthetics and its low rub-off reduces sealant residue from being deposited on glass during common maintenance such as window washing.
This new material complies with sealant standards including ASTM C 920 and ASTM C 719 and the staining/migration specification ASTM C 1248. The medium-modulus sealant provides high movement capability of ±50% in a properly designed joint for long-lasting weathersealing performance.
Dow Corning 756 SMS Building Sealant features excellent unprimed adhesion to common porous substrates and painted metals, making it ideally suited for weathersealing even under challenging conditions. Its one-part formulation, all-temperature gunnability, low stringing and good working/tooling time make it easy for contractors to install.
