POWDER PAINT BINDER COMPOSITION

The invention is directed to a thermosetting powder paint binder composition comprising: a)a polyester comprising at least 75 mol% of isophtalic acid units and b)a crosslinker containing groups capable of reacting with hydroxyl groups and having an aliphatic chain with more than 6 atoms. The polyest...

More Information
Summary:The invention is directed to a thermosetting powder paint binder composition comprising: a)a polyester comprising at least 75 mol% of isophtalic acid units and b)a crosslinker containing groups capable of reacting with hydroxyl groups and having an aliphatic chain with more than 6 atoms. The polyester may comprise 100 mol% of isophtalic acid units. The powder coatings show an improved combination of weathering characteristics and mechanical properties.
