ABSTRACT:
The invention is directed to a thermosetting powder paint composition comprising a thermosetting amorphous polyamide. The amorphous polyamide has a glass transition temperature between 20° C. and 200° C. The polyamide may be a carboxyl-, a hydroxyl- or an amine functional polyamide. A carboxyl functional polyamide has an acid number between 10 and 150 mg of KOH/gram of resin. The invention also relates to a thermosetting powder paint composition comprising a thermosetting amorphous polyamide and an additive comprising a copper halogenide and another halogenide. The invention further relates to a process for coating a substrate at low temperature cure (LTC) conditions and a composition suitable for LTC.
