POWDER COATING COMPOSITION WITH HYDROXYALKYLAMIDE CROSSLINKER

摘要

The invention relates to a powder coating composition comprising as a binder a polymer with free carboxylic acid groups and as a crosslinker a compound containing (beta)-hydroxyalkylamide groups. The crosslinker comprises a combination of at least two compounds containing (beta)-hydroxyalkylamide groups and each compound having different (beta)-hydroxyalkylamide functionalities, the first compound having a (beta)-hydroxyalkylamide functionality of >= 3 and the second compound having a (beta)-hydroxyalkylamide functionality of <= 3.
