High-modulus, two-component window bonding adhesive.
In combination with its good mechanical properties, especially the high modulus of elasticity, the adhesive is particularly suitable for structural bonding of insulating glass units into window frames and for back-bedding applications. It is further suitable for highly demanding industrial bonding and sealing applications.
Sikasil® WT-480 has a wide adhesion range on many substrates such as:
Sikasil® WT-480 is a two component, neutral-curing structural silicone adhesive with very high modulus, for structural bonding of insulating glass units into window frames and for back-bedding applications.
