Abstract

The present invention relates to non-aqueous coating agent compositions, containing at least one polyol (A), at least one silane-modified compound (B) of formula (I), optionally one or more silane-free aliphatic or cycloaliphatic polyisocyanates (C) having free or blocked isocyanate groups, and at least one catalyst (D) for the cross-linking of the silane groups. Furthermore, the non-aqueous coating agent compositions according to the invention can contain one or more surface additives (E) and one or more non-aqueous solvents (F).
