Abstract

The instant invention is directed to a method for bonding one or more substrates by applying adhesives comprising organic polyisocyanates and compounds containing isocyanate-reactive hydrogen atoms which react to form polyurethanes, or moisture-hardening reaction products containing free isocyanate groups or excess quantities of polyisocyanates and compounds containing isocyanate-reactive hydrogen atoms, the improvement wherein said compounds containing isocyanate-reactive hydrogen atoms are dispersions of polymers in organic polyhydroxyl compounds.
