GE SSG4000 UltraGlaze silicone is a one-component, high-strength, neutral cure, elastomeric adhesive sealant tested for structurally glazed curtainwall applications. The material is formulated as a paste which cures into durable and flexible silicone rubber upon exposure to atmospheric moisture. GE SSG4000 UltraGlaze silicone direct bonds to most conventional substrates and finishes including: glass, glass coatings, ceramic frits, fluropolymer and powder coated paints, conversion-coated and anodized aluminum. A key feature and benefit of the GE SSG4000 UltraGlaze Structural Glazing Silicone Adhesive Sealant is its high tear and tensile strength. UltraGlaze SSG4000 Silicone Structural Glazing Sealant is designed for use in structural glazing applications such as in-shop or field glazing of curtain wall modules where glass lights are attached to the metal framing system with the structural sealant. This material can also be used as the weather-seal in glass-to-glass butt joints.
