FEVE Fluoropolymer Resins for High-Performance Coatings What is an FEVE Fluoropolymer??? A hybrid fluoropolymer resin with the ability to be used in standard coatings formulations like any other conventional coating resin A high performance resin that can withstand severe ultraviolet light exposure 2-3 times longer than conventional coatings resins

FEVE Fluoropolymer Resins for High-Performance Coatings Fluoroethylene Vinyl Ether (FEVE) Resins FLUORINATED SEGMENTS: Weatherability, chemical resistance VINYL ETHER SEGMENTS: Gloss, solubility, crosslinking

FEVE Fluoropolymer Resins for High-Performance Coatings Life Cycle Cost Advantages Initial Cost of FEVE-based Topcoat: 5 -10% higher than standard polyurethane topcoat FEVE-based Topcoat Life Expectation: 30 - 60 years Expected Repaints of Std. Polyurethane Topcoat in this Time Frame: 2 to 3 (based on topcoat erosion data from offshore test) Additional Costs of Repaints: facility downtime

FEVE Fluoropolymer Resins for High-Performance Coatings Some things to consider: FEVE polyols can be blended with other polyols to formulate coatings to specific life cycle targets. Lower percentages of FEVE polyols in the formulation will reduce raw material costs compared to 100% FEVE polyol formulations. Coatings formulated for longer life durability will hold their gloss and color better than conventional polyurethane topcoats. This may be an important factor when the appearance of the coating needs to be superior 24/7.

FEVE Fluoropolymer Resins for High-Performance Coatings Conclusion: For 30 years, FEVE resins have been included in exterior coatings for multiple end uses. Their excellent weatherability and corrosion resistance make them attractive for inclusion in topcoats for steel and concrete surfaces. In the long run they can reduce the cost of maintaining both a decorative and a protective finish on many exterior substrates.
