摘要： The invention relates to coating agents which contain: a) at least one hy droxyl group containing compound (A), b) at least one compound (B) with free and/or blocked isocyanate groups, c) at least one catalyst (D) for cross-li nking silane groups, wherein: i) one or more components of the coating agent contain hydrolysable silane groups and ii) the coating agent can be finally hardened to give a coating having randomly distributed regions of an Si-O-S i network. The coating agents according to the invention are characterized i n that the finally hardened coating obtained from the coating agent has a po st-crosslinking index (PCI) of less than 2, the post-crosslinking index (PCI ) being defined as the ratio of the storage modulus E'(200) at 200°C to the minimum of the storage modulus E'(min) at a temperature above the measured g lass transition temperature Tg, the storage moduli E'(200) and E'(min) and t he glass transition temperature Tg being measured using dynamic mechanical t hermal analysis (=DMTA) at a heating rate of 2K/min and a frequency of 1 Hz on free films having a layer thickness of 40 .mu.m +/- 10 .mu.m, which were hardened for 20 min at an object temperature of 140°C and stored after harde ning at 25°C for eight days before the DMTA measurements were carried out.
