There are a whole host of benefits to the utilization of an FEVE resin over a PVDF. These benefits include aesthetic-based benefits, application-based benefits, and sustainability benefits. FEVE (fluoroethylene vinyl ether) was developed to address the shortcomings with traditional fluoropolymer resins like PVDF, they are manufactured by copolymerization of a fluoroethylene monomer with a vinyl ether monomer.

Performance Measurements of Waterbased Coatings Based on Lumiflon FEVE Resins

Testing of waterbased FEVE based coatings has been ongoing in the US for the last several years. Test systems have included waterbased 1K for light industrial, air dry touch-up paint, roof coatings, and even wood coatings as well waterbased 2K systems for DTM and industrial applications. This excerpt focuses on 2K waterbased systems.

High Performance Waterbased FEVE Coatings

LUMIFLON FEVE resins are used in a wide range of applications. This is in part due to the variety of FEVE resins available. Besides the standard solvent based resins, FEVE resins are offered as solid flakes as well as water-based emulsions and dispersions. Achieving the high level of weatherability of a solvent-based resin can be difficult when it comes to water-based systems. Many water-based resins require surfactants which typically increase the hydrophilic nature of the coating resulting in lower weathering performance.

FEVE Resins Among the Top Coatings in AAMA Exposure Tests

The American Architectural Manufacturers Association (AAMA) is a recognized leader in the fenestration industry through product certifications and standards development. A series of AAMA tests have been conducted using organic coatings on aluminum extrusions and panels, resulting in 3 standards by which coatings can be attributed: AAMA2603, AAMA 2604 or AAMA 2605. FEVE resins have been proven to exceed AAMA 2605 standards, which are an excellent choice for coatings for projects that demand high performance materials.
