    Structural Silicone Sealant

    One-Component, Oxime Cure, High Modulus Structural Glazing Sealant
    For structural glazing applications
    READ FULL DESCRIPTION ▼

    TF6999 is a one-component, neutral cure (oxime-type), high modulus silicone sealant engineered for structural glazing applications. It cures by reacting with atmospheric moisture, releasing butanone oxime (methyl ethyl ketoxime) as a by-product, to form a tough, resilient elastomer. Its high modulus formulation delivers superior load-bearing capacity, making it particularly suitable for curtain wall systems where the sealant joint must transfer significant wind loads, dead loads, and thermal stresses. TF6999 provides excellent adhesion to a wide range of substrates commonly used in structural glazing, including glass, anodized and coated aluminum, stainless steel, and other non-porous materials. The oxime cure chemistry offers rapid skin formation and reliable deep-section cure performance.
