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.
Types of Coating Structures:
1. 2/1 Coating:
- Application: The upper surface is coated twice and baked twice, while the lower surface is coated once and baked twice.
- Properties:
- Moderate corrosion resistance and scratch resistance on the single-layer back coating.
- Excellent adhesion.
- Usage: Primarily used for sandwich panels due to its good adhesion properties.
2. 2/1M Coating:
- Application: Both the upper and lower surfaces are coated twice and baked once.
- Properties:
- Enhanced corrosion resistance, scratch resistance, and molding properties.
- Excellent adhesion.
- Usage: Suitable for single-layer compression molding panels and sandwich panels, offering balanced protection and adhesion.
3. 2/2 Coating:
- Application: Both the top and bottom surfaces are coated twice and baked twice.
- Properties:
- Superior corrosion resistance, scratch resistance, and processability.
- Good adhesion, although not ideal for applications requiring extreme adhesion.
- Usage: Commonly used for single-layer pressboards, providing robust protection and durability but not recommended for sandwich panels due to adhesion limitations.
These different coating structures are designed to meet specific performance requirements, ensuring that the color coated coils deliver optimal results in their respective applications.
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.
