Usage of Colour Coated Coils:
Colour coated coils are characterized by their lightweight nature, aesthetic appeal, and excellent anti-corrosion properties. They are designed for direct processing and are available in a range of colors including grey, white, sea blue, and brick red. These coils find extensive application across various industries:
Users can select the appropriate coating based on their specific application needs, ensuring optimal performance and longevity of colour coated coils in diverse environments and industries.
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.
