FEVE resins provide unique properties to the coating system due to alternating copolymer of fluoroethylene and vinyl ether, allowing FEVE based coatings pass AAMA 2065 (American Architectural Manufactures Associations, the highest standard for organic coatings on architectural aluminum extrusions and panels) specifications. When an FEVE resin is introduced into powder coatings with a primer, the system provides noticeable capability for corrosion resistance in metallic substrates. We compare the contribution of various topcoats with different resin chemistry to corrosion protection on metallic substrates. This presentation will provide an introduction to FEVE resin based powder coatings for corrosion resistance applications on metallic substrates.
