Description
Our high-performance Structural Silicone Sealant is engineered for critical structural bonding in building curtain walls, glass facades, and composite panel assemblies. Designed to form a permanent, load-bearing bond with glass, aluminum alloy, metal, and other substrates, it delivers exceptional shear and tensile strength to ensure long-term structural stability. Withstand extreme temperatures (-50℃ to 150℃), UV radiation, ozone, and harsh weather conditions without cracking, hardening, or brittling. Boasting ≥300% elongation at break, it effectively accommodates thermal expansion, contraction, and seismic displacement, while its non-staining formula preserves the aesthetic integrity of decorative surfaces. Available in one-component (moisture-curing) and two-component (fast-curing) options, it supports efficient on-site construction with no specialized equipment required, complying with ASTM, ISO, and GB standards for reliable, code-compliant performance.
Product Feature
1. Resists weak acids, weak bases, detergents, and industrial pollutants
2. High elongation at break (≥300%) and excellent recovery rate
3. Accommodates thermal expansion, contraction, and seismic displacement of substrates
4. Seamless, dense waterproof and airtight sealing to prevent water seepage and dust intrusion
5. Non-staining formula; no yellowing or marks on decorative surfaces (glass, aluminum profiles)
