Application

Sikasil® WT-480 has a wide adhesion range on many substrates such as glass, (coated) metal,wood, polyvinyl chloride (PVC) and many other substrates. In combination with its good mechanical properties, especially the high modulus of elasticity, this makes the adhesive most 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.

Description

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.
