  • Patent number: 7259207
    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.

  • Publication number: 20030130413
    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.

  • Patent number: 5278223
    Abstract: The invention relates to optionally solventless two-component polyurethane surfacers containing finely divided fillers in a high pigment volume concentration based on a polyfunctional isocyanate component (B) and a polyol component (A) which is liquid at room temperature and which consists of mixture components containing isocyanate-reactive hydroxyl groups with an at least predominant content of branched-chain polyols (A1) containing ester and ether groups, which contains at least a proportion of the finely divided fillers and, optionally, the additives and which, for application, is mixed with the isocyanate component (B) and applied as a mixture which can still be processed by shaping.
