What is PVDF Coated Aluminum Coil?

PVDF, or Polyvinylidene fluoride, is a highly durable and weather-resistant polymer. When applied as a coating to aluminum, it creates a protective barrier that shields the metal from UV rays, corrosion, chemicals, and abrasions. This results in a material that is not only strong and lightweight but also retains its color and beauty for decades.

Advantages of PVDF Coated Aluminum Coil

• Exceptional durability and weather resistance: PVDF coatings are known for their ability to withstand harsh weather conditions, including extreme temperatures, UV radiation, and wind. This makes them ideal for outdoor applications where longevity and resistance to the elements are crucial.
• Excellent color retention: PVDF coatings are available in a wide range of colors and finishes, and they are renowned for their ability to maintain their vibrancy and resist fading even after years of exposure to sunlight.
• Lightweight and easy to fabricate: Aluminum is inherently lightweight, and its combination with PVDF coating makes it even easier to handle and install. This translates to reduced labor costs and faster project completion times.
• Low maintenance requirements: PVDF coated aluminum coil requires minimal maintenance, significantly reducing life-cycle costs compared to other materials. Its smooth surface and weather resistance make it easy to clean, and the coating protects the underlying aluminum from corrosion and staining.
• Wide range of colors and finishes: From classic metallic tones to vibrant solids and intricate patterns, PVDF coatings offer a vast array of options to suit any design aesthetic. This allows architects and designers to achieve unique and visually appealing results for their projects.

Today's coil coatings are diverse, with varying properties

By Mike Demko

PVDF coatings have long been considered the highest performing metal paints for exteriors, known for their track record of durability. FEVE is regarded by some to achieve similar performance. These paints are preferable in harsher environments that require the greatest degree of environmental resistance, providing enduring film integrity with long-lasting aesthetic stability despite exposure to UV light, thermal cycles, moisture and other corrosive elements in the environment. Polyester-based paints are typically lower cost and performance, with warranties that reflect that; they are better suited to less-demanding environments. When dealing with coastal and highly demanding environments, even PVDF will not always provide adequate protection against corrosive elements.

PVF Technology

PVF technology is based on a fluoropolymer similar to PVDF in many ways, but with some significant performance benefits. PVF can be formulated as a coating or a film and distinguishes itself as much more robust, durable protection in a number of ways. The first reason is the inherent properties of the PVF polymer, which include unparalleled resistance to chemical corrosion and excellent formability. Compared to other fluoropolymers, PVF is naturally flexible, even without addition of plasticizers or non-fluorinated polymers, ensuring it can bend with formed panels without any risk of cracking.

Other fluorinated materials like PVDF or FEVE require acrylic to be added to achieve a similar level of flexibility, but these additives can compromise the level of chemical resistance and outdoor performance levels. PVF has a significantly tighter bend than other coating systems can achieve, thus ensuring there will be no cracking or weakness on tight bends when panels are fabricated. This ensures that the high level of chemical and corrosion resistance is maintained in the final installed structure. PVF can withstand a vast range of corrosive elements significantly longer than any other coating system, demonstrated through extensive lab testing and real-world exposure data.

PVF film, when used as a replacement for a coil coating system, has some distinct benefits even before application. PVF film is made with a biaxially oriented process, which means the film is stretched in two directions during its manufacture to optimize its mechanical properties. With this approach, if there are any holes or weaknesses in the film, they will be revealed before the film is applied to metal. This stretching process makes the film stronger and tougher, ensuring it exhibits optimal mechanical properties through panel fabrication and in use. Conversely, with coil coatings like PVDF, FEVE or SMP, during the coating process, as the solvent dries off, gas bubbles may form and pop under the paint surface, causing tiny pinholes. These defects can be harder to detect and control than in a web of free-standing polymer film. Over time, corrosive elements like salt water can penetrate these weak areas in the coating and damage the metal beneath.

Evolution

Coil coating technology has evolved slowly over recent years, with contractors and building owners demanding higher levels of performance. The coating is the barrier that protects architectural metal from corrosion, which protects the investment in quality building materials and ensures longevity.

Technologies like PVDF offer excellent protection. However, PVF technology offers warranties superior to even PVDF and ensures a durable and unchanging surface that can withstand even the most challenging environments.

Performance and warranty are just as important as color when choosing the right coating for your project, and are all critical considerations to ensure lasting appearance and protection for your metal building panels. Choosing the optimal durable solution for your environment will lead to longer building lifetime and lower maintenance and replacements, thus reducing material and labor costs, as well as environmental footprint, over the building's life.
