The PVDF coating on the steel sheet is made of polyvinylidene fluoride, a highly durable and weather-resistant material.

PVDF fluorocarbon coating is the best among existing building coatings. As a recognized organic coating with the best protective function, it protects metal building panels from damage and maintains its bright color for decades. To date, PVDF fluorocarbon coatings have been used in buildings worldwide for over 30 years. Today, these buildings remain as good as new. PVDF stands for polyvinylidene fluoride. Fluorine has the highest electronegativity and can form very stable carbon-fluorine bonds; its molecules are unique. Therefore, PVDF has ultra-high stability, unique anti-UV photolysis performance, and extraordinary insulation and mechanical properties.

I. Definition of fluorocarbon coating board:

Fluorocarbon coating board is a colored metal plate made by applying a PVDF fluorocarbon polyester coating to a metal plate and baking it at a high temperature.

II. Features of fluorocarbon coating board:

1. It has ultra-high stability and can maintain various performance stabilities even in severely acidic, alkaline, and polluted environments.

2. Excellent durability; fluorocarbon coating boards can maintain good color and gloss for 20 years outdoors.

3. Excellent processing performance; the coated color steel plate has high toughness and impact resistance and can be processed after embossing.

The PVDF coating on the steel sheet is made of polyvinylidene fluoride, a highly durable and weather-resistant material. This coating effectively resists ultraviolet radiation, moisture, and other environmental factors, making it suitable for both indoor and outdoor applications.

PVDF fluorocarbon color-coated steel sheets are known for their excellent color retention and vibrant appearance. Even under harsh weather conditions, the PVDF coating ensures that the color remains vibrant and does not fade easily, providing lasting aesthetics and protection.

In addition to aesthetics, PVDF fluorocarbon color-coated steel sheets also have excellent durability. It is highly resistant to scratches, abrasion, and corrosion, ensuring long-term performance and minimizing maintenance requirements.
