Polyester and its use in powder coating

A polyester containing carboxyl groups, based on a substantially aromatic dicarboxylic acid mixture and a substantially aliphatic diol mixture, having an acid number between 10 and 26 mg KOH/g, a hydroxyl number that is smaller than 15 mg KOH/g, a theoretical number-average molecular weight between...

Zusammenfassung:	A polyester containing carboxyl groups, based on a substantially aromatic dicarboxylic acid mixture and a substantially aliphatic diol mixture, having an acid number between 10 and 26 mg KOH/g, a hydroxyl number that is smaller than 15 mg KOH/g, a theoretical number-average molecular weight between 4,500 and 12,500 and also a glass transition temperature between 40 and 85 DEG C.
