The present invention relates to a mixture (M) employable as hardener and as adhesion promoter containing at least two different isocyanate-containing components (M1) and (M2) that are each independently of one another free and/or blocked, and optionally an additional component (M3) that is different from (M1) and (M2), wherein (M1) comprises at least one aliphatic polyisocyanate and (M2) comprises at least one aliphatic, polyether unit-containing polyisocyanate, wherein the relative weight ratio of (M1) to (M2) to each other in (M) is within a range of 25:1 to 3:1, each relative to the solids content of (M1) and (M2), and at least one of the components (M1), (M2) and optionally (M3) contained in (M) contains hydrolyzable silane groups, use of (M) as hardener and adhesion promoter in a coating composition, such a coating composition, and method for at least partial coating of a substrate with a filler coat and for at least partial coating of a substrate with a multilayer coating. |
