| Abstract: | According to the ageing of outdoor powder coatings,recent developments of weather durable polyester powder coating at home and abroad are introduced.The developing directions such as synthesis and modification of basic resin,selection of curing system and curing agent and employment of suitable additives are discussed.Moreover,the related mechanisms of weather resistance are analyzed simply.As main ingredients of powder coating,performances of polyester resin and curing agent have a vital function on its weatherability.The use of nano-additives is described as a new and effective method for weather durable powder coating. |
| Keywords: | polyester powder coating weather resistance ageing synthesize and modification of basic resin curing agent nano-additives |
