Nickel PTFE Coating
Nickel PTFE, also known as Nye-Tef™, is a food-grade composite coating solution exclusive to Electro-Coatings, for applications requiring exceptional resistance to friction and peak performance in coating adhesion. PTFE or Teflon is known for its self-lubricating properties, and PTFE coatings are one of the world's most friction-free coatings.
Nye-Tef™ combines the self-lubricating properties of PTFE with the high wear resistant hardness of electroless nickel, and has excellent adhesion which allows for an increased control on uniform thickness. The PTFE coatings self-lubricating properties make it an ideal surface treatment for components and assemblies that cannot use conventional lubricants.
The PTFE in the plated layer provides excellent release from calcium found in hard water areas. In combination with the corrosion resistance of the layer, it offers a solution to the age-old problem of scale build-up on heating elements and sprays nozzles.

Electroless Nickel PTFE (Nye-Tef™) Process
Electroless nickel PTFE composite coating consists of an autocatalytic alloy applied nickel/phosphorus matrix containing submicronic particles of PTFE (polytetrafluoroethylene). The PTFE, while soft in its natural form, becomes exceptionally durable when suspended in the nickel matrix. A hardness of 50Rc, combined with the natural friction resistance of Teflon coating, or PTFE, yields a surface that can resist significant abrasion over a long working life.
The coating's non-crystalline molecular structure adds resistance to corrosion and wears due to abrasion. The use of electroless nickel with the ptfe coating surface delivers a coating with excellent adhesion and extremely uniform coating thickness. Documented accuracy to +/- 10% ensures consistent coverage. The non-electrolytic application technology of Nye-Tef™ provides a completely uniform coating, including full coverage of hidden surfaces or intricate geometries.
