Abstract:
A nonaqueous, heat curable, two-component coating comprising:A) a solvent-containing polyol component; and B) a cross-linking component comprising a cross-linking agent prepared by reacting at least one of an aliphatic and cycloaliphatic polyisocyanate having 2 to 6 NCO functional groups per molecule with at least one of an N-alkyl-3- aminopropyltrialkoxysilane and an N-aryl-3-aminopropyltrialkoxysilane, wherein said nonaqueous, heat curable, two-component coating contains at least 18% by weight of a solvent or a mixture of solvents, from 0.1 to 95 mol % of said isocyanate groups originally present in the polyisocyanate are reacted with at least one of said N-alkyl-3- aminopropyltrialkoxysilane and said N-aryl-3-aminopropyltrialkoxysilane, and said polyol of component A and said cross-linking agent of component B are in a weight ration of from 6:1 to 1:2.
