Nonaqueous thermocuring two component coating

摘要

Nonaqueous heat curable coating agent (I) comprises (A) a solvent containing polyol component and (B) a cross-linking component comprising at least one (cyclo)-aliphatic polyisocyanate (NCO functionality of 2-6) whereby 0.1-95 mol.% of the isocyanate groups are reacted with N,N,-bis-(3-trialkoxysilylpropyl)amine and the weight ratio of (A):(B) is 6:1-1:2 based on non-volatile organic components. A nonaqueous heat curable two component coating agent (I) comprises (A) a solvent containing polyol component and (B) a cross-linking component comprising at least one aliphatic and/or cycloaliphatic polyisocyanate having an NCO functionality of 2-6 whereby 0.1-95 mol.% of the original free isocyanate groups of the polyisocyanate are reacted with N,N,-bis-(3-trialkoxysilylpropyl)amine and the weight ratio of (A):(B) is 6:1-1:2 based on non-volatile organic components.
