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.
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.
