  • Heat-setting mixtures which have a long shelf life and comprise a polyisocyanate and compounds which are reactive toward isocyanate groups, and their preparation
    Patent number: 4525570
    Abstract: In heat-setting mixtures which have a long shelf life at room temperature and comprise a polyisocyanate and one or more compounds which are reactive toward isocyanate groups, the polyisocyanate is present, in the form of discrete particles, in a saturated or unsaturated amino-, hydrazide-, mercaptan- and/or carboxyl-containing polymer, polycondensate or polyadduct which has a functionality of more than 1 and some of which can be replaced by a polyol, and the polyisocyanate particles are deactivated at their surface so that from 0.01 to 20 equivalent percent of the total amount of isocyanate groups present is deactivated. These mixtures are useful as coating compositions, adhesives and sealant materials, particularly as undersealants for motor vehicles.
