SS911 Very High Performance Silicone Weather-Proof

DESCRIPTIONSS911 Very High Performance Silicone Weather-Proofing Sealant is a one-component high movement capacity (±50%) neutral curing silicone sealant designed and tested for weather-proof sealing in curtain wall joints, especially in high-rise curtain wall joints, big-size glass or metal panel curtain wall joints, complex construction curtain wall joints and situations with high seal requirement. The material is supplied as a paste, which cures into a durable, formed-in-place silicone rubber joint sealant upon exposure to atmospheric moisture. CHARACTERISTICS High movement capacity (±50%), more suitable for weather-proof sealing in high-rise curtain wall joints, big-size glass or metal panel curtain wall joints, complex construction curtain wall joints and situations with high seal requirement than common silicone sealants 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 sealants APPLICATIONS Weather-proof sealing in high-rise curtain wall joints; Weather-proof sealing in big-size glass or metal panel curtain wall joint; Weather-proof sealing in complex construction curtain wall joints; Weather-proof sealing in situations with high seal requirement; Weather-proof sealing in other curtain wall joints.TYPICAL PROPERTIES Property Result Test method As SuppliedColor Black, gray, white Tack free time(23°C/73°F, 50% RH) 42 minutes ASTM C679 Curing Time 23ºC (73ºF) at 50% RH 7-14 days Full Adhesion14-21 days Flow, Sag or Slump 0.1 inches max ASTM D2202 Working Time 10-20 minutes Specific Gravity 1.32 As CuredDurometer Hardness, Shore A 27 ASTM D2240 Ultimate Tensile Strength 1.10MPa ASTM C1135 Ultimate Elongation 430% ASTM C1135 Joint Movement Capability ±50% ASTM C719 Specifications: Typical property data values should not be used as specifications.
