Abstract

The invention relates to thermosetting powder compositions which give coatings proving remarkable weatherability, excellent mechanical properties and an outstanding flow containing a binder which comprises a mixture of amorphous polyesters (A) containing from 50 to 100 mol % of isophthalic acid and from 70 to 100 mol % of neopentyl glycol, and (B) which comprises from 75 to 100 mol % of at least one straight-chain saturated di-carboxylic aliphatic acid having from 4 to 14 carbon atoms and from 75 to 100 mol % of at least one branched chain aliphatic diol.
