Coil coating prolongs the service life of finished products and improves the use value. Coil coatings have excellent decoration, protection and durability. Generally, coil coatings are made of polyester resins with excellent light resistance, weather resistance and impact processability, acrylate resins and fluorocarbon modified polyesters, and silicone modified polyester resins as the main materials. Crosslinkers can be selected with high weather resistance, hardness and flexibility. Methyl etherified amino resins with good properties, or aliphatic blocked isocyanate resins, have high post-processing resistance.
