Painted 20-50um Top Coat PVDF HDP SMP RMP

40 -275g Zinc HDGI / Galvanized Color Coated Steel Coil

Product Description:

Colour coated coil is a versatile product made from substrates like hot-dip galvanized sheet, hot-dip aluminium zinc plated sheet, and electro-galvanized sheet. The manufacturing process involves pre-treatment, including chemical degreasing and chemical conversion treatment, followed by coating one or several layers of organic paint. This paint is then baked and cured to achieve a durable and aesthetically pleasing finish. These coils are named colour coated coils due to the various colours of organic paint applied.

Using hot-dip galvanized steel strip as the substrate for colour coated steel strip provides a dual layer of protection. Besides the zinc layer, the organic coating adds an extra shield, enhancing rust prevention and extending the steel strip's service life by about 1.5 times compared to regular galvanized strips.

Technical Parameters:

The selection of coatings for colour coated coils is dependent on the specific environmental conditions in which they will be used. Various types of resins are utilized to ensure optimal performance. Here are the coatings that are commonly used:

• Polyester: This coating offers good adhesion, rich colours, formability, and outdoor durability at a low cost.
• Silicone Modified Polyester (SMP): Provides good film hardness, abrasion resistance, heat resistance, exterior durability, and resistance to chalking. It also retains gloss well and has general flexibility at a medium cost.
• High Durability Polyester (HDP): Known for excellent colour retention, UV resistance, exterior durability, and chalking resistance. It also has good film adhesion, rich colours, and provides excellent cost performance.
• Polyvinylidene Fluoride (PVDF): Known for exceptional colour retention, UV resistance, outdoor durability, chalking resistance, solvent resistance, and dirt resistance. It offers good formability but is available in limited colours and comes at a higher cost.

Due to their diverse applications and exceptional characteristics, colour coated coils remain a popular choice in various industries. They offer a combination of functionality and aesthetic appeal.

Colour coated coils have different coating structures that are utilized based on their intended purpose. Here are the common types of coating structures:

• 2/1: This structure coats the upper surface twice and lower surface once and bakes twice. It has good adhesion and is mainly used for sandwich panels.
• 2/1M: This structure coats the upper and lower surfaces twice and bakes once. It offers good corrosion resistance, scratch resistance, and molding properties. It is a suitable choice for single-layer compression molding panels and press boards.
• 2/2: This structure coats the top and bottom surfaces twice each and bakes twice. It has good corrosion resistance, scratch resistance, and processability. It is mostly used for single-layer press boards and has good adhesion.

Overall, the coating selection and structure of colour coated coils are critical factors that determine their performance and effectiveness in various industries.
