<p>Polyurethane adhesive composition comprises (a) 5-60 wt.% of a binder comprising a silyl group-terminated polyurethane, and (b) 40-95 wt.% of solid particles of an organic material, where the silyl group-terminated polyurethane is obtained by (i) polyaddition of a composition comprising a polyether polyol with an excess of a diisocyanate and (ii) then reacting the product of step (i) with a stoichiometric amount or excess of an alpha -,beta - or gamma -aminosilane, and has at least two terminal isocyanate groups. An independent claim is included for producing an article comprising an agglomerate of organic solid particles containing a crosslinked polyurethane binder, comprising forming the polyurethane adhesive composition and then crosslinking by heating in the presence of water at a temperature of 100-150[deg] C.</p> |
