Xylan is a fluoropolymer-based industrial coating. Generally, it is applied in a thin film to the target material.
Xylan is generally used to reduce friction, improve wear resistance, and for non-stick applications. Additionally, it can be used to protect a metal from corrosion. The most commonly known application is in non-stick cookware but Xylan coatings have also been used extensively in the automotive industry and for corrosion protection in the oil and gas industry.
Xylan is the umbrella trademark for most of the Whitford Corporation fluoropolymer coatings line. Xylan is made of low friction, wear resistant composites of fluoropolymers and reinforcing binder resins. Xylan® coatings can be one-, two- (primer and top-coat), and three- (primer, mid-coat, top-coat) coat conventional and reinforced (filled) coating systems.
The fluoropolymers utilized in Xylan coatings consist of PTFE, PFA, and FEP. The properties listed below may not apply to all Xylan coatings as the fluoropolymer and resin content and type can have significant effects on each property.
