DESCRIPTION

SS621 Silicone Structural Glazing Sealant is 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.
