PVDF/Kynar

PVDF – Kynar

Polyvinylidene Fluoride (PVDF) or Kynar® coating is a pure thermoplastic fluoropolymer that is non-reactive and possesses multiple coating benefits. Kynar coating is a chemical resistant, thick film barrier coating primarily used on chemical processing equipment due to it’s low weight and low thermal conductivity.

This coating is unaffected by most chemicals and solvents, and has excellent wear and abrasion resistance. PVDF coatings are especially resistant to solvents, acids and heat, and has low density compared to similar fluoropolymers. Kynar PVDF coatings also have a high dielectric strength, excellent resistance to weathering elements in harsh environments. Along with the ability to self extinguish, PVDF generates little smoke in the event of a fire.
