A Comprehensive Reveal of The Advantages And Disadvantages of PVDF And FEVE Fluorocarbon Coatings

In recent years, the price of PVDF fluorocarbon coatings has soared, leading to a continuous rise in the production cost of fluorocarbon color-coated sheets, which has brought a heavy burden to downstream users. Against this background, many coating and color coating manufacturers are actively seeking strategies to reduce costs. At this time, FEVE fluorocarbon coating, as a new competitor, has gradually emerged and become a new star in the field of color coating. But what exactly is FEVE? What are the similarities and differences between it and PVDF? Let's explore in depth.

Introduction to PVDF Fluorocarbon Coating

Characteristics and Advantages of PVDF

The fluorocarbon color-coated sheet that we often refer to mainly refers to the color-coated sheet using PVDF fluorocarbon coating. PVDF, namely polyvinylidene fluoride resin, is a high-performance organic coating material. It is widely regarded as the best protective coating among existing color-coated sheet coatings. It can effectively protect color-coated sheets from damage and maintain bright colors for a long time. PVDF is an organic coating material with excellent performance, widely praised for its outstanding corrosion resistance and anti-aging properties, and it performs well even in large open engineering projects.

However, in recent years, the price of PVDF resin has soared, leading to a significant increase in the cost of PVDF fluorocarbon coatings, which has brought enormous cost pressure to color coating production. Despite its recent price increase, it is still used in key construction projects to ensure long-lasting protection and aesthetics.

Introduction to FEVE Fluorocarbon Coating

Basic characteristics of FEVE

FEVE, the English abbreviation for fluorinated olefin-alkyl vinyl ether copolymer resin or fluorinated olefin-alkyl vinyl ester copolymer resin, is also often referred to as trifluoroethylene or tetrafluoroethylene. Compared with PVDF, the coating formed by high-temperature application of FEVE coating has excellent gloss and hardness, as well as scratch resistance. FEVE is a new type of fluorocarbon coating material, known for its excellent gloss and hardness, and also has good scratch resistance. However, its weather resistance is slightly inferior to that of PVDF, and its adhesion is also slightly weaker.

Performance comparison between FEVE and PVDF

However, in terms of weather resistance,The QUVA artificial accelerated aging performance of FEVE coating is 4000-5000 hours, while that of PVDF coating can reach 4000-8000 hours. In addition, it is worth noting that the adhesion of FEVE coating is slightly insufficient compared with PVDF coating. The T-bend performance of FEVE coating is about 2-3T, which is equivalent to that of PE polyester coating, while PVDF coating can achieve a better 0-1T. FEVE coating is superior to PVDF in terms of gloss and hardness, but inferior in terms of aging resistance and adhesion. There is no absolute distinction between the two; the choice should depend on specific application requirements.

At present, our understanding of FEVE fluorocarbon coatings is still limited to the application field of color-coated  sheets, and the attention it has received has only gradually increased recently. To obtain more comprehensive data, it is necessary to continuously accumulate experience in practical engineering applications.
