High-performance PVF metal sheets are here, free from PFAS restrictions.

DuPont Tedlar PVF metal sheetis currently an ideal choice superior to PVDF metal sheets in the market. This product is jointly developed by DuPont and Simon Aluminum. The PVF coated metal sheet is made of highly stable fluororesin material, which effectively protects the surface of the metal sheet from external attacks. Itseasy cleanability,color retention,corrosion resistanceanddurabilityfar exceed that of PVDF metal sheets.

Theeasy cleanabilityis one of its unique advantages. Due to the strong inertness of the PVF coating, it is not easily reactive with other substances, has a smooth surface, does not easily collect dust, and can restore its original bright appearance with simple cleaning. The following image compares the PVF project with ordinary fluorocarbon projects,Shanghai Sports Center uses PVF: The cleaning effect is significantly different.

At the same time, the PVF coating also has acid and alkali resistance and salt spray resistance, which can maintain its good performance in harsh environments. The superior dielectric properties and crystallinity of PVF mean that it is more resistant to acids, alkalis, and solvents than any other coatings (PVDF, SMP, FEVE, PE, or PU).

AndPVDF contains plasticizers,which makes it brittle, easily causing paint cracks when bent, and it is also prone to contamination, thus failing to protect the metal surface. In contrast,PVF does not contain plasticizers, has higher toughness, chemical resistance, and weather resistance, thus providing more durable protection for the metal surface against harsh environments.

In addition, the PVF coating also has excellent UV resistance. Long-term UV exposure has almost no effect on its surface, allowing the building's exterior to maintain its beauty and durability for a long time. In contrast, the lifespan of PVDF sheets is only 20 years, while PVF coated sheets canprotect building surfaces for over 50 years.

More importantly,no PFAS was used in the manufacturing process of PVF(permanent chemicals), which can enter the human body through food, drinking water, air, packaging, etc., causing health risks. Several countries and organizations have issued bans requiring polluting companies to be held legally responsible. PVF has been verified to not fall under the market regulatory bans of many countries and organizations. Therefore, PVF has also become a viable alternative to other PFAS-containing materials.

So far, PVF coating projects have been applied in many projects around the world. One example is the permanent site of the Top Scientists Forum in Lingang, Shanghai. PVF coating was used on the aluminum panels at the eaves and entrance of the building. The choice of PVF was made because the building is close to the sea, and it needs to ensure that it canresist corrosion from seawater salt spray.

In summary, PVF metal sheets are far superior to PVDF metal sheets in terms of easy cleanability, corrosion resistance, and durability. Choosing PVF metal sheets as protective materials for building surfaces not only ensures long-term aesthetics but also provides more durable protection.
