Color-coated coils are based on hot-dip galvanized sheet, hot-dip galvanized sheet, electro-galvanized sheet, etc. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of organic coatings are applied on the surface, and then A product that has been cured by baking. Color coating roll application Color-coated coils are light, beautiful and have good anti-corrosion properties, and can be directly processed. The colors are generally divided into gray-white, sea blue and brick red. They are mainly used in advertising, construction, household appliances, electrical appliances, furniture and transportation. Industry. The paint used in the color-coated coil selects the appropriate resin according to the use environment, such as polyester silicon modified polyester, polyvinyl chloride plastisol, polyvinylidene chloride, etc. Users can choose according to the purpose.vcoating structure type 2/1: Apply twice on the upper surface, once on the lower surface, and bake twice. 2/1M: Coat the upper and lower surfaces twice and bake once. 2/2: Coat the upper and lower surfaces twice, and bake twice. v Uses of different coating structures: 2/1: The corrosion resistance and scratch resistance of the single-layer back paint are poor, but it has good adhesion, mainly. To be applied to sandwich panels; 2/1M: The back paint has good corrosion resistance, scratch resistance and processability, and has good adhesion. It is suitable for single laminate and sandwich panels. 2/2: The corrosion resistance, scratch resistance and processability of the double-layer back paint are better, and most of them are used for single-layer paint. Laminated board, but its poor adhesion, not suitable for sandwich panels.
