How is PVDF coating applied?

PVDF spray coating uses a diaphragm pump or a plunger pump to apply pressure and static electricity for spraying. The powder coating is sprayed by shaking or inhaling, and electrostatic powder is sprayed on the gun mouth. Drying of PVDF can be both natural leveling drying and baking.

What is a PVDF coating?

PVDF coating (polyvinylidene fluoride) or Kynar® coating is a pure thermoplastic fluoropolymer that is non-reactive and possesses multiple coating benefits. Kynar® PVDF coatings for steel, aluminum, and other metals also have a high dielectric strength, excellent resistance to weathering elements in harsh environments.

How is PVDF manufactured?

How PVDF is produced? PVDF (homopolymers and copolymers) is generally synthesized by the free radical polymerization of 1,1-difluoroethylene (CH2=CF2). The polymerization takes place in the suspension or emulsion from 10-150°C and pressure of 10-300 atm. The material obtained is then processed into film or sheets.

What is PVDF coating on aluminum?

PVDF coating of uniform and excellent quality has a metallic luster, bright colour and strong three-dimensional sense. PVDF coating has excellent anti-fading, anti-frosting and anti-air pollution (acid rain, etc.) corrosion due to its stable chemical properties and good adhesion effect.

Can PVDF be applied to steel?

PVDF coatings are applied to various metal substrates including aluminum, carbon steel and stainless steel.

Is PVDF thermoset or thermoplastic?

What type of thermoplastic is PVDF in particular? PVDF is a semi-crystalline, high purity engineering thermoplastic, meaning its molecular structure is highly ordered.

Is PVDF powder coating?

PVDF coating is a resin based liquid coating system. Powder Coating is an electrostatic process in which the electrostatically charged powder is sprayed on the metal surface. PVDF coatings have higher durability than Powder Coatings. Powder Coatings are stronger than PVDF Coatings.

How is Kynar paint applied?

When Kynar is used as a coating, most of the time it is applied via electrostatic powder coating.
