COATINGS CONSISTING OF SPECIAL POLYOLS AND OXALIC ACID

摘要

The present invention relates to coated substrates obtained by stoving mixtures containingA) 1 part by weight of ester group-free polyols having an OH content of 1 to 10%,B) 0.05 to 1 part by weight of oxalic acid andC) 0.2 to 5 parts by weight of organic solvents,at temperatures of 120° C. to 250° C. and a stoving time of 1 to 100 min on substrates. The present invention also relates to a process for preparing the coated substrates.
