〣Product description

The color-coated steel strip using hot-dip galvanized steel strip as the base material is protected by zinc layer, and the organic coating on the zinc layer plays the role of covering and protecting, preventing the steel strip from rusting, and the service life is about 1.5 times longer than that of galvanized steel strip.

〣Color coated rolls for use

Color coated roll has light weight, beautiful appearance and good corrosion resistance, and can be directly processed. The color is generally divided into white and white, blue, brick red, mainly used in advertising, construction, home appliances, electrical appliances, furniture and transportation industries.

Color coating volume coating according to the use of different environment to choose suitable resin, such as polyester silicon modified polyester, PVC plastic sol, polyvinylidene chloride and so on. Users can choose according to the use.

〣coating structure

Type of coating structure

2/1: Apply twice to the upper surface, once to the lower surface, and bake twice.

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

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

v Uses of different coating structures:

2/1: Single layer back paint corrosion resistance, scratch resistance is poor, but has good bonding, main

To be applied to sandwich plate;

2/1M: Back paint corrosion resistance, scratch resistance and processing formability is good, with good bonding

Suitable for use with single - layer molded plate and sandwich plate.

2/2: Double layer back paint corrosion resistance, scratch resistance and processing formability is better, most used for single

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