ABSTRACT:
A pasty single component polyurethane adhesive is provided. The NCO terminated polyurethane prepolymer is substantially linear, contains from 2.0% to 8.0% based on the weight of the prepolymer, of highly disperse silica and up to 10% by weight, based on the weight of the prepolymer, of additives. The one component adhesive has an Expressed Volume of at least 2,000 g/min measured according to DIN EN 29048 and a Creep Resistance measure according to DIN EN 27390 below 6.0 after 5 minutes.
