What is PVDF surface treatment?
PVDF coatings are one of the most common types of industrial coatings in use today. This type of coating is created by polymerizing vinylidenedifluoride. It’s a specialty plastic that belongs to the family of fluoropolymers and is used in applications that require high levels of purity and strength, as well as those that require excellent resistance to acids, solvents, bases, and heat. PVDF has a fairly low melting point, which can be beneficial as well in certain applications, although it does mean that this material is not properly suited for some applications.
In the fluorocarbon coating process, a 2-coat or 3-coat system is applied electrostatically to the product, using coatings made of PVDF fluoropolymer resin and inorganic ceramic pigments, which is then heated to polymerise and cure the coating.
These PVDF coatings do not react to most chemicals and solvents and have very good wear-abrasion resistance. PVDF coatings are considered one of the most durable coatings by far as they can last for decades without chalking or fading
