POWDER COATINGS BASED ON BRANCHED OLIGOESTERS AND NON-EMISSIVE URETDIONE POLYISOCYANATES |
| 摘要 |
The present invention relates to powder coating compositions which can be cured at low temperatures. The powder coating composition of the invention includes a unique combination of a branched oligoester polyol and uretdione cross-linking agent which when cured results in a coating binder with desirable hardness, flexibility, solvent resistance, corrosion resistance, weatherability and gloss.
