    摘要: Disclosed are coating compositions comprising (a) at least one hydroxyl-containing compound (A), (b) at least one compound (B) having free and/or blocked isocyanate groups, and (c) at least one catalyst (D) for the crosslinking of silane groups, where (i) one or more constituents of the coating composition contain hydrolyzable silane groups and (iii) the coating composition can be finally cured to a coating which has statistically distributed regions of an Si—O—Si network. The finally cured coating obtained from the coating composition has a post-crosslinking index (PCI) of less than 2, wherein (PCI) is 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 glass transition temperature Tg.
