  • Hybrid polyester-fluorocarbon powder coating composition and a method for coating a substrate with such composition
    Patent number: 11053394
    Abstract: The present invention provides a hybrid polyester-fluorocarbon powder coating composition which is a dry blend of a polyester powder coating composition A and a fluorocarbon powder coating composition B, wherein: —polyester powder coating composition A comprises a first polyester polymer and a curing agent for the first polyester polymer; and —fluorocarbon powder coating composition B comprises a fluorocarbon polymer, a curing agent for the fluorocarbon polymer, and a second polyester polymer and a curing agent for the second polyester polymer; wherein the weight ratio of polyester powder coating composition A and fluorocarbon powder coating composition B is in the range of from 25:75 to 75:25, wherein the first polyester polymer is a carboxyl functional polymer having an acid value in the range from 18 to 70 mg KOH/g polymer and wherein the second polyester polymer is a hydroxyl functional polyester polymer having a hydroxyl value in the range of from 70 to 350 mg KOH/g polymer.
