Abstract: The present invention provides a 1-component polyurethane adhesive composition based on at least one NCO-terminated polyurethane prepolymer, which comprises polyamide fibers and at least 10% by weight of fillers.

Abstract: Polymer dispersions containing water, at least one water-dispersible polymer, and at least two ions or elements selected from the group consisting of Li, Ba, Sr, B, Co, Cu, Mn, Mo, Ni, Ag, Pb, Zn, W, La, Ce and Sn or salts thereof. The ions or elements are present in the dispersion in amounts of at least 10 ppm.

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.

Abstract: 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.

Abstract: The invention relates to a pasty single-component polyurethane adhesive based on at least one polyurethane pre-polymer with an NCO terminal and at least one thickener, in addition to optionally at least one additive. According to the invention, A) the polyurethane pre-polymer with an NCO terminal is substantially linear, B) the thickener is a highly disperse silicic acid in a concentration of between 2.0 and 8.0% by weight in relation to the pre-polymer, and C) the additive constitutes less than 10% by weight in relation to the pre-polymer. The invention thus fulfils the practical requirements for an adhesive used for construction and assembly, both in terms of fluidity and non-sag properties.
