Abstract: The present invention relates to processes for preparing compact transparent polyurethanes by mixing (a) isocyanates with (b) compounds having at least two isocyanate-reactive groups, (c) catalysts, and optionally (d) auxiliaries and additives to give a reaction mixture and carrying out reaction to the compact transparent polyurethanes, the isocyanates (a) comprising at least 50 wt % of biurets of hexamethylene diisocyanate. The present invention further relates to a compact, transparent polyurethane prepared by a process of the invention, and to the use of such a compact, transparent polyurethane as a surface coating, more particularly in the interior of means of transport.
