THERMOPLASTIC POLYESTER COMPOSITION FOR POWDERED PAINT

摘要

A thermoplastic polyester composition for a powdered paint which comprises: (a) a copolyester derived from a dicarboxylic acid component comprising 40 to less than 60 molar % of terephthalic acid and a diol component comprising at least 70 molar % of 1,4-butanediol and having a melting point determined by differential thermal analysis of 100 DEG to 150 DEG C., (b) a nucleating agent, and (c) a leveling agent. This composition can be applied with a lowered pre-heat temperature and a lowered heat setting temperature and can form a coating film having an excellent adhesion, a good appearance and a high impact resistance.
