SY-9900 Curtain Wall Silicone Structural Sealant: Key Advantages Compared to Ordinary Structural Sealants

The common structural adhesives on the market generally have shortcomings such as insufficient strength, easy aging, and poor adaptability. When used for long-term applications in curtain wall projects, they are prone to problems like delamination, cracking, yellowing, and water seepage, failing to meet the load-bearing and weather resistance requirements of high-rise buildings, and posing significant safety risks. In contrast, the dual-source SY-9900 curtain wall silicone structural adhesive has been specifically upgraded with a targeted formula, completely outperforming ordinary structural adhesives. It is a high-end curtain wall project-specific high-performance product.

Compared to ordinary structural adhesives, SY-9900 adopts a high-purity neutral silicone formula, without corrosion and low odor. It is compatible with various curtain wall substrates such as coated glass, insulating glass, aluminum alloy, and stone, and can firmly bond without the need for a primer. The product has high strength and high resilience, capable of withstanding wind pressure, self-weight, and thermal expansion and contraction deformations of the curtain wall, preventing delamination and detachment. It also has extreme weather resistance and anti-aging properties, capable of withstanding temperature differences ranging from -40℃ to 150℃, resisting ultraviolet rays, rain, and ozone erosion. It does not yellow, crack, or powderize over a long period of outdoor use, with a lifespan of up to several decades. The curing speed is balanced, the construction is smooth without impurities, and it balances construction efficiency and project safety, making it the preferred structural adhesive for curtain walls, sunroofs, and sunrooms.
