Brief Introduction

Colour coated coil is a product made from hot-dip galvanised sheet, hot-dip aluminium zinc plated sheet, electro galvanised sheet, etc., which is pre-treated (chemical degreasing and chemical conversion treatment) and then coated with one or several layers of organic paint and subsequently baked and cured. Because of the coating of different colours of organic paint coloured steel coil and so named, referred to as colour coated coil.

The use of hot-dip galvanised steel strip as the substrate of the colour coated steel strip in addition to the zinc layer protection, the zinc layer on the organic coating plays a role in covering and protecting the steel strip to prevent rust, the service life of the steel strip is longer than the galvanised strip, about 1.5 times.

Colour Coated Coil Usage

Colour coated coil has light weight, beautiful and good anti-corrosion properties, and can be directly processed, the colour is generally divided into grey and white, sea blue, brick red, mainly used in advertising, construction, home appliance industry, electrical appliances industry, furniture industry and transport industry.

The coatings used for colour coated rolls are selected according to the use of different environments with suitable resins, such as polyester silicone modified polyester, polyvinyl chloride plastisol, polyvinylidene chloride and so on. Users can choose according to the use.

Coating Structures

Type of coating structure

• 2/1: Coat upper surface twice, lower surface once, bake twice.

• 2/1M: Coat upper and lower surfaces twice, bake once.

• 2/2: Top and bottom surfaces are coated twice each and baked twice.

Usage of different coating structures:

• 2/1: The corrosion resistance and scratch resistance of single layer back coating is poor, but it has good adhesion, mainly used for sandwich panels.It is mainly used for sandwich panels;

• 2/1M: backcoat with good corrosion resistance, scratch resistance and moulding properties, good adhesion, suitable for single-layer compression moulding panels.

• 2/1M: good corrosion resistance, scratch resistance and moulding properties, good adhesion, suitable for single-layer pressboards and sandwich panels.

• 2/2: double-layer backing paint with good corrosion resistance, scratch resistance and processability, mostly used for single-layer pressboards, but with good adhesion.

Most of them are used for single-layer moulding board, but its adhesion is not good, and it is not suitable for sandwich board.
