PVDF - KYNAR®
PVDF, or PolyVinyliDene Fluoride, is a semicrystalline,
thermoplastic fluoropolymer.
Why PVDF Kynar®?
PVDF, or PolyVinyliDene Fluoride, is a semicrystalline, thermoplastic fluoropolymer. The brand we at Marcote use is Kynar®.
Carbon – Fluorine molecular bonds are exceptionally strong and they provide PVDF with stability. Combine these with an equal number of Carbon – Hydrogen bonds, which provide solubility, and you have a particularly useful fluoropolymer coating.
PVDF is recognised as being mechanically stronger than other fluoropolymers such as PTFE. A key property that makes PVDF stand out for industrial use is its resistance to ultraviolet light (UV) and high-energy radiation. Thus, PVDF can be found in nuclear waste processing plants.
Its high dielectric strength, abrasion resistance and thermal stability make it useful for cable and wire isolators as well as for batteries and electrical sensors.

Why Settle for Standard When PVDF Can Do More?
Too many manufacturers accept coatings that “just about cope” with their operating environment, until early wear, chemical attack, or UV degradation forces costly downtime and replacements.
At Marcote, we challenge that compromise. PVDF (Kynar®) isn’t just another fluoropolymer, it’s a solution engineered to perform where others fail.
From resisting harsh chemicals in processing plants to standing up to extreme UV exposure in outdoor environments, PVDF coatings extend component life, reduce replacement frequency, and safeguard critical assets.
If your current coating is eating into margins through premature failure, PVDF may be the smarter investment. With Marcote, you don’t just get a coating, you get a strategy to cut costs, minimise downtime, and improve performance across the board.
