Powder coating composition comprising a co-reactable particulate mixture of carboxylic acid group-containing polymers and beta-hydroxyalkylamide curing agent |
摘要 |
A thermosetting powder coating composition which has good handling properties and which has a good bland of physical properties such as appearance, flexibility, hardness, solvent resistance, corrosion resistance and exterior durability is disclosed. The composition comprises a co-reactable particulate mixture of a carboxylic acid group-containing acrylic polymer, a second carboxylic acid group-containing polyurethane having sufficient crystallinity to assist in flow of the powder coating compositions, a beta-hydroxyalkylamide crosslinking agent and an amorphous acid group-containing polyurethane.
