BRANCHED POLYESTER CONTAINING POWDER COATING COMPOSITION

摘要

The invention relates to binder comprising a crosslinker that is reactive with acid-functional polyester and a branched, partially defunctionalized acid-functional polyester, wherein the polyester is based on: a. At least one multi-functional component that is either carboxyl- functional, hydroxyl- functional or carboxyl- and hydroxyl- functional; b. At least one di-functional component that is reactive towards a functional group on the multi-functional component; and c. At least one mono-functional component; wherein the multi-functional component does not contain a tertiary carboxylic functionality and at least 50% of the acid-derived groups originate from an aromatic acid.
