More Information
Summary:Provided are thermosetting powder coating compositions which upon application to a substrate and curing provide coatings having superior weathering, impact, and flexibility properties. The compositions are a blend of an amorphous resin having cycloaliphatic diol residues, a semicrystalline resin, and a crosslinker. The binder portion of the composition may be either hydroxyl or carboxyl functional or a mixture thereof. Also provided are shaped or formed articles coated with the cured compositions.
