PVDF stands for Polyvinylidene Fluoride. A PVDF coating, or KYNAR500 coating, is a pure thermoplastic fluoropolymer that is non-reactive and contains a long list of coating benefits. It is a factory-applied resin-based liquid coating system. The distribution of metal particles in fluorocarbon coatings has a direct impact on the appearance of the coating.A short fluorine-carbon bond is formed in the chemical structure of the paint, which forms the strongest bond with the hydrogen ion. Fluorocarbon coatings are therefore characterized by certain physical and chemical properties, which we will discuss in a bit more detail later on.
PVDF coatings are sold under several brand names, including Kynar, Hylar, and Solef, but Aluwell®ACP panels are made of 70% KYNAR 500 certified PVDF (Fluorinated polyvinyl) paint which conforms to ASTM (American Society for Testing and Materials) and EN (European Nation) standards. We procure PVDF paints from Nippon, PPG, Bergers, Akzonobel, Monopol & many other paint companies.

What is the most suitable application of PVDF-coated ACP panels?
PVDF coatings are widely used for projects that require an extremely durable coating that resists weathering, chalking, fading, and UV rays while offering excellent protection to the substrate.
PVDF coatings are especially recommended for exterior locations with strong sunlight or moist and humid areas, such as coastal locations and beaches.
The outer aluminum sheet of the ACP panel meant for exterior application is usually coated with PVDF paints.
ACP panels with PVDF coating can be used to decorate storefronts, shopping malls, industrial facilities, educational institutes, bus stations, advertisement screens, signage, display systems, hospitals, and curtain wall cladding of buildings.
What are the Advantages of using ACP cladding with PVDF coating?
PVDF coating properties such as low melting point, high dielectric and mechanical strength translate into the following advantages. Here is a quick glance.
Excellent resistance to acids, solvents, bases
Superb resistance to abrasion and wear
High peel-off strength
Outstanding color and gloss retention
Coats surfaces with an appealing matte finish
Exceptional color consistency (resists fading)
An alternative to dip coatings, which contain organic compounds (VOCs)
Thermo stable both at low and high temperatures
Highly inert and stable, providing excellent resistance from metal weathering over time.
Anticorrosive and non chalking
Ensures long-term durability with minimal maintenance
Anti-frosting and anti-air pollution (acid rain, etc.)
High brightness despite the thin coating (.020″ – .030″ )
Can withstand atrocious Weather
Anti-UV and anti-nuclear radiation
Two hours of resistance to boiling water (good adhesion effect)
Low smoke generation and self-extinguishing capabilities in case of fire

Conclusion
The type of coating you should use may depend on your exact applications, but if you require highly durable, environmentally friendly, and long-lasting ACP panels, PVDF coatings may be the ideal choice for you.
Aluwell® 's PVDF-coated ACP panels are free of lead, mercury, chromium, or any other heavy metal compounds since these elements are anything but ecosystem-friendly. Moreover, the PVDF coatings we use impart anti-ageing properties to the ACP cladding.
