Abstract:
The present invention relates to polyurethane/ureas wherein the polyurethane/ureas contain 0.5 to 6% by weight, based on the weight of the polyurethane/ureas, of alkoxysilane groups (calculated as Si, MW 28), which have been incorporated by the reaction of isocyanate groups with a dihydroxy compound containing urea and alkoxysilane groups, and wherein the polyurethane/ureas optionally contain hydrophilic groups and are optionally dispersed in an aqueous medium.The present invention also relates to a process for preparing these polyurethane/urea and to their use for preparing coatings.
