Versatile Binders for Elastic Adhesives based alpha-Silane-Terminated Polyethers

摘要

Where bonded joints are subjected to dynamic loads, adhesives are needed which cure to form a strong, yet elastic material. Recently, alpha-silane-terminated polyethers have become available as binders for elastic adhesives. These hybrid polymers, a completely new development from Wacker Silicones, impart high tensile strength combined with good and adjustable elongation at break. The new binders are notable for their low viscosity, are easy to process, crosslink extremely quickly and have no known harmful effects.
