(PVDF), excellent colour retention and UV resistance, excellent outdoor durability and chalking resistance, excellent solvent resistance, good formability, dirt resistance, limited colours, high cost.

Colour Coated Coil Usage: 

These color coated coils are primarily used in the construction industry for applications such as building roofs, walls, and steel structure plants. They are also widely employed in the manufacturing of home appliances, purification and clean plants, and other industrial fields. The product’s versatility makes it suitable for a variety of uses, ensuring both aesthetic appeal and functional durability.

Commonly used specifications for color coated sheet coils range in thickness from 0.2mm to 1.0mm. The typical domestic widths are 1000mm and 1200mm, while the main export dimensions include 940mm, 1200mm, 1219mm, and 1250mm. These variations in size cater to different market needs and application requirements, providing flexibility for diverse project specifications.

Coating Structures: 

Coating structures refer to the specific application methods and baking processes used to apply protective coatings to surfaces, enhancing their durability and performance. Here are the detailed descriptions of common coating structures:

1. 2/1 Coating Structure:
   • Description: The upper surface is coated twice, while the lower surface receives one coating layer. The coated surfaces undergo two rounds of baking.
   • Characteristics: Offers moderate corrosion resistance and scratch resistance. Known for its strong adhesion properties.
   • Applications: Primarily used in sandwich panel construction where adhesion is critical for bonding layers.
2. 2/1M Coating Structure:
   • Description: Both the upper and lower surfaces are coated twice, followed by a single round of baking.
   • Characteristics: Provides good corrosion resistance, scratch resistance, and molding properties. Ensures strong adhesion to substrates.
   • Applications: Suitable for single-layer compression molding panels and versatile enough for use in pressboards and sandwich panels.
3. 2/2 Coating Structure:
   • Description: Both the top and bottom surfaces receive two coats of paint, each followed by two rounds of baking.
   • Characteristics: Offers high corrosion resistance, scratch resistance, and excellent processability due to the dual-layer coating.
   • Applications: Predominantly used in single-layer pressboards where robust protection and superior adhesion are required.
