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.

Single-component polyurethane adhesive

A one-pack polyurethane adhesive containing a polyisocyanate prepolymer and at least one aminoether polyol, having a molar ratio of ether groups to amino nitrogen in the aminopolyether polyol of 7 to 30.

Fast setting 1k-polyurethane glue

A polyurethane prepolymer obtainable by reacting at least one aromatic polyisocyanate having symmetrical substitution of NCO groups and at least one aromatic polyisocyanate having asymmetric substitution of NCO groups, the fraction of aromatic polyisocyanate having symmetrical substitution of NCO groups being higher than the fraction of polyisocyanate having asymmetric substitution of NCO groups, and at least one polyol having an OH functionality of more than 2.5 and at least one polyol having an OH functionality of less than 2.5.
