Product Features
The Main Purpose
01

The Two-Component Structural Silicone Sealant represents a pinnacle of engineering for modern architectural glazing systems. Specifically formulated for the demanding requirements of structural assembly in glass curtain walls, this high-performance sealant is indispensable for both prefabricated unitized curtain wall construction and insulating glass manufacturing.

02

Its primary application lies in the factory-controlled, precision bonding of curtain wall unit glass to its supporting metal frameworks—such as aluminum mullions, transoms, and brackets. This process creates a high-strength, durable bond that is critical for transferring wind loads, seismic forces, and the glass's dead weight from the glass panel to the metal substructure and ultimately to the building's framework.

Instructions For Use
01

To ensure good adhesion of silicone structural adhesive, the surface of the bonded material must be clean, dry, and free of dirt.

02

Apply low viscosity tape to the areas that require protection, and trim and remove the tape before the adhesive has cured.

03

Users can adjust the curing speed by changing the mixing ratio according to their actual needs.

04

Users must determine the suitability of the product themselves and conduct on-site compatibility bonding tests to confirm whether the product has good adhesion with the substrate and whether the interface is truly full.
