Classification of polyester resins for powder coatings

powder coating polyester resin has a variety of classification methods, according to its type of officer group can be divided into argon-based polyester and hydroxy-type polyesterThe type of carnitine-based polyester molecular chain contains either end-of-the-argon-based or side-basedIt is most widely used, whether it is a hybrid powder coating or pure polyester powder coating seamount polyester resinHydroxy polyester resin molecular chains contain endoxorxorxorhexyls or side hydroxylsIt can be used in conjunction with isocyanate curing agents or amino resin curing agents to manufacture powder coatingsPowder coatings obtained with isocyanate curing agents such as B-1530 are called polyurethane powder coatings, and powder coatings made with powder-based resincurors (Powderlink-1174) resins should be called polyester ammonia powder coatings, not polyurethane powder coatingsVestagon B-1530 curing agent is a closed isocyanate cross-linking agent, the main component is hexylamide closed isocantidon di isocyanate part of tripolymerPowderlink-1174 is an ammonia resin cross-linking agent, the main component is monomer tetra-methamphetamine
