Abstract

Copolymers of vinylidene fluoride and hexafluoropropylene are well known for their chemical resistance and high purity. Extruded piping, molded parts, and sheet linings find extensive use in chemical process applications. A new powder coating has been developed which is based on this copolymer resin to augment existing products and applications. This powder coating is easy to apply, particularly for odd-shaped parts, and can be applied at high thicknesses (>2.5 mm). This powder coating can be a cost-effective alternative to stainless steel and glass linings. A description of the coating process and selected applications are presented. Chemical exposure data are also presented, comparing this functional fluoropolymer powder coating with uncoated stainless steel.
