SILICONE SEALANTis a one-component, high strength neutral curing silicone sealant designed and tested for structurally glazed curtain wall applications. The material is supplied as a paste, which cures into an extremely tough elastomeric silicone rubber ensuring a durable, flexible, watertight bond upon exposure to atmospheric moisture.
CHARACTERISTICS
High strength and high elongation
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)
Successfully tested for use in protective glazing applications
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
Meets global standards for structural glazing (American, China, Europe)
APPLICATIONS
Silicone structural glazing in curtain wall; such as factory glazing of unitized curtain wall systems or in field constructed stick curtain wall systems.
Structural attachment of many panel systems.
Protective glazing applications.
Panel stiffener applications.
