<p>An adhesive composition comprising a two component polyurethane binder comprising a polyol base part comprising a catalyst and a low viscosity solvent-free MDI hardener, wherein the polyol base part has a viscosity &lt;10,000 mPa·s. (Brookfield RTV 3/20 at 23°C and 50% R.H.) shows improved water and wearing resistance. Furthermore, the composition has a relatively long open time and a very short curing time when activating the catalyst.</p> |
