PVDF coated aluminum coil is a type of aluminum coil that has been coated with a PVDF (Polyvinylidene fluoride) paint，uses fluorinated polymer resin as the main ingredient. This highly durable, weather-resistant coating is known for its high-quality finish, excellent adhesion, and resistance to fading, chalking and cracking.
PVDF coated aluminum coil is a popular material for architectural decoration, exterior cladding, building facades, roofing systems, interior decoration and signage applications due to its vibrant colors, outstanding gloss, and long-lasting performance. PVDF paint is guaranteed about 10-15 years. It is mainly used for high-grade buildings or buildings in harsh environments, especially in chemical industry, metallurgy and other industries, as well as coastal humid areas, high UV areas and areas with serious pollution and corrosion.
There are several types of PVDF coated aluminum coil including solid, metallic, stone and wood grain finishes. Solid finishes are the most widely used and are available in a wide range of colors. Metallic finishes give the appearance of real metal and provide a distinctive look to buildings. Stone finishes mimic natural stone, while wood grain finishes imitate the look of real wood.

Types of PVDF Coating
With KYNAR500 PVDF, two or three times for coating and baking, has good properties of anti-acid, anti-alkali and is durable in atrocious weather and environment, keeping 15 years no unwonted fading. In view of these facts, we recommend this panel applied for external wall cladding.
Which different with traditional PVDF is the clear coating. It contains nanometer element, which can protect panel from pollution, Because nanometer has self-cleaning effect, It easy to get rid of dust and pollution by raining or water.

Color Options of PVDF Coated Aluminium Sheet:
PVDF coated aluminum coils can be processed into a variety of different colors and textures such as metallic color, wood grain color, marble color, etc. by special surface treatment technology to meet different architectural styles and decoration requirements.
The standard color of PVDF coated aluminum coils is modulated according to the Ral color card. The basic colors are red, yellow, blue, green, white, gray and other colors and their derivative colors, which are suitable for most conventional applications.
The Metallic color of PVDF color coated aluminum coils simulate metal textures, such as silver gray, bronze, rose gold, etc., which add a sense of luxury and class to the product and are often used in high-end architectural decoration.
The printing series achieve natural texture effects such as wood grain and stone grain through special coating technology, providing more diversified choices for architectural design, esuitable for places that pursue natural and environmental protection concepts.
