Abstract:
The invention relates to hybrid polyester-fluorocarbon powder coating composition and the manufacture thereof. These powder coating compositions are manufactured in a process comprising the steps of: Preparation of a polyester powder coating composition A, comprising a polyester resin and a curing agent for said polyester resin; Preparation of a fluorocarbon powder coating composition B, comprising a fluorocarbon resin and a curing agent for said fluorocarbon resin; and Dry blending said polyester powder coating composition A and fluorocarbon powder coating composition B, wherein the weight ratio of polyester powder coating composition A to fluorocarbon powder coating composition B is in the range of 70:30 to 30:70.
