Different colors of organic paint color steel coil

Color coated coil is a product of hot galvanized plate, hot aluminum plated zinc plate, electrogalvanized plate, etc., after surface pretreatment (chemical degreasing and chemical conversion treatment), coated with one or several layers of organic coating on the surface, and then baked and cured. Also because coated with a variety of different colors of organic paint color steel coil thus named, referred to as color coated coil.

In addition to the zinc layer protection, the organic coating on the zinc layer covers and protects the steel strip to prevent rust, and the service life is about 1.5 times longer than that of the galvanized strip.

Color coated roll use

Color coated roll has light weight, beautiful appearance and good corrosion resistance, but also can be directly processed, the color is generally divided into gray, blue, brick red, mainly used in advertising, construction, home appliance industry, electrical appliance industry, furniture industry and transportation industry.

The paint used in the color coating volume is selected according to the different use environment, such as polyester silicon modified polyester, polyvinyl chloride plastisol, polyvinylidene chloride and so on. Users can choose according to the use.

Coating structure

v Type of coating structure

2/1: Paint the upper surface twice, paint the lower surface once, bake twice.

2/1M: Paint the upper and lower surfaces twice and bake once.

2/2: Paint the upper and lower surfaces twice, bake twice.

v Uses of different coating structures:

2/1: The single-layer back paint has poor corrosion resistance and scratch resistance, but it has good adhesion, main

To be applied to sandwich panels;

2/1M: The back paint has good corrosion resistance, scratch resistance and processing formability, and has good bonding

Suitable for use with single molded and sandwich panels.

2/2: The double-layer back paint has good corrosion resistance, scratch resistance and processing formability, most of which are used for single

Laminated plate, but its adhesion is poor, not suitable for sandwich plate.

Color coated roll coating types

Polyester (PE)

Good adhesion, rich color, wide range in terms of formability and outdoor durability, medium chemical resistance, low cost.

Silicon-modified polyester

Namely (SMP), the hardness, property and heat resistance of the coating film is good, as well as good external durability and resistance to powder, gloss retention, flexibility is general, and the cost is medium.

High durability polyester

Namely (HDP), excellent color retention and UV resistance, excellent outdoor durability and powder resistance, good film adhesion, rich color, etc.

Polyvinylidene fluoride

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