SS611 Silicone Weather-Proofing Sealant

DESCRIPTIONSS611 Silicone Weather-Proofing Sealant is a one-component neutral curing silicone sealant with excellent adhesion, weatherability and elasticity for weathersealing in curtainwall and building facades. It easily extrudes in any weather and quickly cures at room temperature by reaction with moisture in the air to form a durable, flexible silicone rubber seal.CHARACTERISTICS Extension/compression movement capability of up to ±25% of the original joint width Odorless, non-corrosive cure system Excellent weatherability and high resistance to ultraviolet radiation, heat and humidity, ozone and temperature extremes Remains flexible over a temperature range of -55°F (-48°C) to 250°F (121°C) Excellent unprimed adhesion to wide range of substrates including coated, enameled and reflective glasses, anodized and polyester coated or painted aluminum profiles including most fluoropolymerbased paints Good compatibility with other neutral silicone sealantsAPPLICATIONS Weather sealing in glass curtainwall joints; Weather sealing in metal, enamel curtainwall joints; Sealing in expansion joints for concrete, plastic and metal etc.; Sealing in roof joints; Many other uses.
