Abstract

The present invention relates to moisture-curing hotmelt adhesive compositions which comprise at least one silane-functional polyurethane prepolymer of the formula (I). The compositions have neither heating nor curing bubbles and feature an exceptional viscosity stability at high temperatures. These hotmelt adhesives are therefore suitable especially for industrial manufacture and especially of transparent materials.
