Generally, it is applied in a thin film to the target material to improve its durability and non-stick properties.
DuPont, at that time focused on improving housewares, developed important properties of nonstick coatings through research.
DuPont scientists found that adding Fluorinated ethylene propylene to the hard, adhesion-promoting binder resins produced one-coat products that were more durable than earlier Teflon formulations.
[1] Xylan is generally used to reduce friction, improve wear resistance, and for non-stick applications.
Xylan is made of low friction, wear resistant composites of fluoropolymers and reinforcing binder resins.
