Product Introduction
Exterior Structural Sealant is high-performance neutral silicone structural bonding & sealing glue engineered for building external walls, curtain wall projects and high-altitude outdoor construction. Different from low-load indoor structural adhesives, it features core advantages of heavy-load structural bonding, all-weather weather resistance, UV resistance, wind-load deformation resistance and long-term waterproof & crack-proof performance. It serves as essential functional adhesive for exterior panel fixation, joint sealing and facade protection.
Core Product Advantages
- Engineering-grade high load-bearing for safe overhead installation: Specially formulated high-modulus silicone for exterior use meets engineering requirements on tensile and shear strength, forming tough high-strength elastic bonding layer after full cure.
- All-weather anti-aging durability for long outdoor service: Formulated with imported UV, aging and ozone-resistant additives to withstand extreme temperature swings, rain erosion, acid rain and salt-spray corrosion.
- Non-corrosive neutral formula to protect substrates: Pure neutral curing system with no pungent odor, no corrosion and no oily bleed-out. Compatible with mixed exterior materials for clean, long-lasting neat facade finish.
- Excellent workability for outdoor construction: Single-component ready-to-use without mixing or dilution; smooth body with easy extrusion and outstanding thixotropy to avoid sagging on vertical and overhead high-rise surfaces.
