Abstract

Disclosed is the production of isocyanate-based or silane-functional adhesive and/or coating materials in the form of reactive single-component granulates and the use thereof. In particular, the reactive one-component coating-material and/or adhesive granules of the include at least one isocyanate-reactive starting polymer and at least one diisocyanate and/or polyisocyanate. Optionally, the granules of the invention may further include at least one catalyst and/or at least one wax and/or at least one resin and/or at least one preferably non-isocyanate-reactive polymer. The granules of the invention may contain an excess of diisocyanate and/or polyisocyanate which amounts to 0.5% to 30 w %, and is preferably generated by free terminal isocyanate groups.
