DESCRIPTION
SS911 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.

LIMITATIONS
SS911 Very High Performance Silicone Weather-Proofing Sealant should not be used, applied or is not recommended:
In structural glazing applications or where the sealant is intended as an adhesive.
In areas where abrasion and physical abuse are encountered.
In totally confined spaces as the sealant requires atmospheric moisture for cure.
On frost-laden or damp surfaces
To building materials that bleed oils, plasticizers or solvents – materials such as impregnated wood, oil-based caulks, green or partially vulcanized rubber gaskets or tapes.
In below-grade applications
On substrates made of polypropylene, polyethylene, polycarbonate and polytetrafluoroethylene.
Where movement capability greater than ±50% is required.
Where painting of the sealant is required, as the paint film may crack and peel
For structural adhesion on bare metals or surfaces subject to corrosion (i.e., mill aluminum, bare steel, etc.)
To surfaces in contact with food
For use underwater or in other applications where the product will be in continuous contact with water.
