Abstract
A storage stable adhesive paste composition is described. It contains a plurality of first solid particles comprising a surface protected polyisocyanate and a plurality of second solid particles of polymer having functional groups that react with the polyisocyanate. The particles may be protected by encapsulation in a layer of a material that is not reactive to the polyisocyanate. Preferably, the protective layer also is not reactive to the polymer having functional groups that react with the polyisocyanate. The polyisocyanate particles also can be protected by a layer formed by chemically reacting said polyisocyanate particles with isocyanate reactive compounds to form a protective surface layer around said polyisocyanate particles.
