Application

The main production processes of the color coated coils includes pre-treatment process, coating process, and baking process.

Production Process: Uncoiling-degreasing-washing-passivation-drying-cooling-painting-drying and curing-cooling

The top finish coating is larger than 20μm to prevent the intrusion of corrosive media. Due to the different anti-corrosion mechanisms of primer and finish coating, not only the total coating thickness should be guaranteed, but also the thickness of primer (>5μm) and finish coating (>15μm).

PVDF pre-painted steel coil requires a thicker coating. It provides a longer service life. The requirements for the backside paint coating depend on the application, and the sandwich panel only requires a layer of primer. The formed steel plate requires two coats. The thickness is at least greater than 10 μm.

Coating color: according to the user's needs to choose (common colors are white gray, aquamarine, ivory, scarlet, orange, dark soybean green, brick red, etc.)
