Color-coated coil is 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 is baked and cured. It is named after the colored steel coils coated with various colors of organic coatings, referred to as color-coated coils

Color coated roll use

Color-coated rolls are light, beautiful, and have good anti-corrosion properties, and can be processed directly. The colors are generally gray, sea blue, and brick red. They are mainly used in advertising, construction, household appliances, electrical appliances, furniture, and transportation. Industry.

The coating used for color-coated coils should select appropriate resins according to different use environments, such as polyester silicon-modified polyester, polyvinyl chloride plastisol, polyvinylidene chloride, etc. Users can choose according to the purpose.

Type of coating

Polyester (PE)

Good adhesion, rich colors, wide range in formability and exterior durability, moderate chemical resistance, low cost.

Silicon modified polyester

That is (SMP), the coating film has good hardness, wear resistance and heat resistance, as well as good external durability and chalking resistance, gloss retention, general flexibility, and medium cost.

High Durability Polyester

That is (HDP), excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, good film adhesion, rich colors, excellent cost performance.

Polyvinylidene fluoride

Namely (PVDF), excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, excellent solvent resistance, good formability, dirt resistance, limited color, high cost.
