APPLICABLE STANDARDS: 50HM C/T882，ISO11600-G-50HM，ASTM C 920 Class 50
One-part, high movement capability (±50%) neutral curing silicone sealant specially developed and tested for weatherproof sealing in curtain wall joints, especially in high-rise & supertall curtain wall joints, big-sized glass or metal panel curtain wall joints, complicated 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.

Weatherproof sealing in high-rise & supertall curtain wall joints; Weatherproof sealing in big-sized glass or metal panel curtain wall joint; Weatherproof sealing in complicated construction curtain wall joints; Weather-proof sealing in situations with high seal requirement.
LIMITATIONS:
Do not use for structural glazing. Not recommended for building materials that bleed oils, plasticizers, or solvents–materials such as impregnated wood, oil-based caulks, green or partially vulcanized rubber gaskets or tapes. Not recommended for use in totally confined spaces as the sealant requires atmospheric moisture for cure. Not recommended for continuous water immersion applications. Not recommended for use on frost-laden or wet surfaces. Not recommended for places where painting of the sealant is required, as the paint film may crack and peel. Do not apply at temperatures below 4°C or above 40°C.
