Color-coated steel strips using hot-dip galvanized steel strip as the base material, in addition to the zinc layer protection, also have an organic coating on the zinc layer that provides coverage and protection, preventing rust and extending their service life by approximately 1.5 times compared to galvanized strips.
Applications of Color-Coated Coil: Color-coated coils are lightweight, aesthetically pleasing, and offer good corrosion resistance. They can also be directly processed. Colors are generally available in gray-white, sea blue, and brick red, and they are mainly used in the advertising, construction, home appliance, electrical appliance, furniture, and transportation industries.
The coatings used for color-coated coils are selected based on the appropriate resin, such as polyester silicone-modified polyester, polyvinyl chloride plastisol, and polyvinylidene chloride. Users can choose according to their application.
Coating Structure: Coating Structure Types:
2/1: Two coats on the top surface, one coat on the bottom surface, two baking cycles.
2/1M: Two coats on both the top and bottom surfaces, one baking cycle.
2/2: Two coats on both the top and bottom surfaces, two baking cycles.
Applications of different coating structures:
2/1: Single-layer back coating has poor corrosion resistance and scratch resistance, but good adhesion. Mainly used in sandwich panels.
2/1M: Back coating has good corrosion resistance, scratch resistance, and processability, and good adhesion. Suitable for single-layer profiled sheets and sandwich panels.
2/2: Double-layer back coating has good corrosion resistance, scratch resistance, and processability. Mostly used in single-layer profiled sheets, but its poor adhesion makes it unsuitable for sandwich panels.
