ABSTRACT

Fluoroethylene vinyl ether (FEVE) resin is the only curable and powder coating process friendly fluoropolymer which can pass AAMA 2605 (the highest standard for organic coatings on architectural aluminum extrusions and panels by the American Architectural Manufacturers Association). Coatings based on FEVE resin provide superior weatherability, corrosion and chemical resistance due to resin’s unique chemistry.  Our new powder coating technology has been focused on creating customer values through new formulation development. This presentation will focus on low cost FEVE/polyester blending technology:  a coating blends of 30% FEVE resin and 70% superdurable polyester can be stratified into two distinct layers with FEVE clear coating on the surface as a protective layer. Metallic pigments can be incorporated in the FEVE/polyester blends and form a unique structure with metallic flakes staying in the interface of FEVE and polyester. The blends can meet the requirements of AAMA 2605. New formulations with improved coating flexibility and surface quality will be discussed.
