What is PVDF Coating

PVDF coatings are one of the most common types of industrial coatings in use today. Recently it is more popular for protective coating for aluminum windows over power coating OR anodizing.

“PVDF stands for “Polyvinylidene Fluoride” coating (also referred as  PVF2 coatings).”

PVDF  is a chemical resistant barrier coating made of a composite fluoropolymer resin and ceramic pigment.PVDF coating is created by polymerizing vinylidene difluoride. PVDF is based on a minimum of 70% Kynar 500 or Hylar 5000 resin. PVDF coating is applied to ferrous and non ferrous materials to provide protection from the ambient environment and can last decades without the coating fading.Compared to other fluoropolymers, PVDF coating has an easier melt process because of its relatively low melting point of around 177 °C.

Advantages of PVDF coating

1. Chemistry is based on Carbon – Fluorine Bond, the strongest in the Universe.

2. excellent   durability   i.e.   excellent   resistance   to   Fading   and   Chalking   (because   of   inert   ceramic pigmentation and the resin does not absorb the damaging Ultraviolet radiation)

3. Outstanding resistance to harsh environmental pollutants

4. Excellent resistance to acids, alkalis and salts

5. Low maintenance due to low dirt pick up and non staining surface

6. Low mildew and bacterial staining

7. Very good abrasion and impact resistance, with very low erosion

8. Excellent corrosion resistance
