THERMOSETTING COATING COMPOSITION AND USE THEREOF AS FINISH COATING

Thermosetting coating compsn. is based on a binder combination of (a) prepolymer contg. butanone oxime-blocked NCO gps. and having a mol.wt. of 1000-10000, which is based on (cyclo)aliphatic polyisocyanates and organic cpds. contg. OH gps.; (b) a hardener component, consisting of cycloaliphatic poly...

Zusammenfassung:	Thermosetting coating compsn. is based on a binder combination of (a) prepolymer contg. butanone oxime-blocked NCO gps. and having a mol.wt. of 1000-10000, which is based on (cyclo)aliphatic polyisocyanates and organic cpds. contg. OH gps.; (b) a hardener component, consisting of cycloaliphatic polyamine(s) with ≥ 2 prim. amino gps. in an equiv. ratio of blocked NCO gps. to amino gps. of 1:(0.8-1.2); and opt. (c) usual additives. The novelty is that the OH cpds. comprise (i) 50-90 OH equiv.-% OH-contg. polyesters, (ii) 10-50 OH equiv.-% OH-contg. polyacrylate resins and/or alkoxylated bisphenol A with an average of 2-4 alkylene oxide units/mol. and (iii) 0-30 OH equiv.-% other organic poly-OH cpd..
