Hybrid polymers for adhesive bonds

Wacker presented its first-ever hybrid polymers for structural adhesive bonds, last month, at the World Adhesive & Sealant Conference WAC2012.
The novel polymers are based on the alpha-silane technology and are available as grades of the new Geniosil XB product line. They cure on contact with atmospheric moisture to form thermosets, thus achieving the high Shore-D strength needed for structural adhesives. This provides adhesives manufacturers with an alternative to traditional binder materials.
Adhesive binders based on Geniosil XB pose no health risks, meet high technical requirements and offer manufacturers a wide range of formulation options.
The product line is a range of alpha-silane-terminated polyethers. The polymers are of low viscosity and feature a high density of crosslinkable silyl groups. This high silyl group density produces a close-meshed three-dimensional network on curing. Adhesives based on Geniosil XB can be applied and processed just like conventional polyurethane-based products.
