    Curtain Wall Weatherseal

    One-Component, Oxime-Based Neutral Cure, Class 35 High-Movement Silicone Sealant
    For curtain wall weathersealing and high-movement building joints
    READ FULL DESCRIPTION ▼

    TF6998 is a one-component, oxime-based neutral cure, high-performance silicone sealant engineered for curtain wall weathersealing and high-movement building joints. It cures upon reaction with atmospheric moisture to form a durable, elastic seal, releasing methyl ethyl ketoxime as a by-product during cure. With a Class 35 movement capability (±35%), it accommodates significant joint expansion and compression in glass curtain walls, aluminum composite panels, terracotta facades, and other demanding building envelope applications. Following accelerated artificial aging tests, TF6998 exhibits no significant degradation in its key physicochemical properties, demonstrating excellent long-term durability and UV resistance.
