Product Description

The BaiYun SS621 Black Silicone Structural Sealant is a premium one-component neutral curing silicone engineered for structurally glazed curtain walls and demanding construction projects. Supplied in a convenient 590ml sausage pack, it cures upon exposure to atmospheric moisture into an extremely tough, elastomeric silicone rubber. This ensures a durable, flexible, and watertight bond for professional glaziers, facade contractors, and large-scale panel installations.

What Makes BaiYun SS621 Suitable for Structural Glazing Applications?

Unlike standard sealants used for simple gap filling, structural silicones transfer loads and stresses across bonded joints. BaiYun SS621 is specifically formulated for silicone structural glazing in curtain walls and the structural attachment of panel systems. It meets or exceeds ASTM C1184 standards, ensuring the necessary tensile strength, elongation, and modulus for reliable performance in critical structural bonds where glass and aluminum components are directly bonded to the building framework.

What Performance and Durability Features Does It Offer?

Excellent weatherability provides high resistance to ultraviolet radiation, heat, humidity, ozone, and temperature extremes. Once fully cured, it maintains stability across a wide range from -58°F to 302°F. Cured properties include 45 Shore A durometer hardness, 1.30 MPa tensile strength, and 300% elongation. The neutral-cure system is odorless and non-corrosive to metals, making it safe for anodized aluminum and coated glass.

How Does the Sausage Pack Format Benefit Large-Scale Applications?

The 590ml sausage pack is designed for efficiency in professional, large-volume applications. Unlike standard cartridges requiring frequent changes, this larger format allows continuous application with fewer interruptions, saving valuable time on large curtain wall projects. Used with a specialized sausage gun, it dispenses smoothly and consistently into joints. The foil pack collapses as sealant is dispensed, minimizing waste.

What Are the Key Curing and Working Time Specifications?

As a one-part RTV silicone, it cures by reacting with moisture in the air. At standard conditions of 73°F and 50% relative humidity, working time is 10-20 minutes. It becomes tack-free in 30-60 minutes and achieves full cure in approximately 14-21 days. The low VOC formula under 25g/L suits environmentally conscious projects. With specific gravity of 1.34 and less than 0.1mm sag, it remains in place on vertical surfaces.

What Substrates and Applications Is It Recommended For?

Applications include silicone structural glazing in curtain wall construction, structural attachment of panel systems, protective glazing applications, and panel stiffener applications. It exhibits excellent adhesion to glass and aluminum when surfaces are properly prepared. For structural glazing, manufacturer review of shop drawings and adhesion tests on project-specific substrates is essential.

What Are the Storage and Shelf Life Requirements?

When stored at or below 80°F in original unopened containers, usable life is 12 months from manufacture date. Do not use on surfaces below 50°F or above 104°F, in totally confined spaces where moisture cannot reach the sealant, or on materials that bleed oils, plasticizers, or solvents.
