Title: HOT CURING OR HEAT-ACTIVATED COMPOSITION CONTAINING A SURFACE-DEACTIVATED POLYISOCYANATE
Abstract:
The invention relates to curable compositions comprising at least one specific blocked amine, at least one surface-deactivated polyisocyanate that is solid at ambient temperature and optionally water or a water-producing substance. Compositions of this type are characterised by an extremely high storage stability as long as they are not heated. Hot curing compositions that cure with the action of heat can thus be produced. Heat-activated compositions can also be produced. When heat is applied the latter compositions are not cured but are activated so that they are able to cure under the influence of moisture. The curable compositions are particularly suitable for use as adhesives.
