Kynar 500 PVDF Resin-Based Coatings Outperform FEVE

Tests show that Kynar 500 resin-based finishes outperform coatings based on the fluoropolymer resin commonly known as fluorinated ethylene vinyl ether (FEVE). The reason: coatings formulated with FEVE claim to be 100% fluoropolymer resin, but actually contain far less fluorine than Kynar 500 resin-based coating formulations. Because the C-F bond is one of the strongest bonds known, the higher percentages of fluorine content in a coating results in superior, long-term protection. The charts on this page show the fluorine content and the Florida weathering performance of the two technologies.

Fluorine Content of Formulated Coatings

In typical formulations (see shaded areas), Kynar 500 resin-based coatings contain higher fluorine levels than FEVE-based coatings, resulting in greater resiliency, color and gloss retention.
