Electroless Nickel Plating with PTFE
PEN-TUF®/EN (Co-Deposited Electroless Nickel with PTFE) or Electroless Nickel Plating with PTFE
PEN-TUF®/EN is an Electroless Nickel Composite coating containing particles of PTFE evenly dispersed in a Nickel Phosphorus matrix. During the plating process the PTFE particles are suspended in the Electroless Nickel bath creating a uniform co-deposit.
By combining the lubricity of PTFE with many features of Electroless Nickel, PEN-TUF®/EN is able to meet a broad range of engineering applications. PTFE is one of the most lubricious materials available and when co-deposited with Electroless Nickel it provides a superior wear coating with a coefficient of friction around 0.1. The Electroless nickel content of our PEN-TUF®/EN coatings ensures uniform coating thickness, corrosion resistance, and durability. Typical thicknesses of the coating range between .0001-.0004”. If a thicker coating is required an undercoat of Electroless Nickel can be applied.
PEN-TUF®/EN can be applied to a variety of substrates, including steel, stainless steel, aluminum, titanium, copper, magnesium and brass to improve the performance of moving parts used in high speed/moderate load carrying applications.

Advanced Surface Technologies Infused PEN-TUF®/EN is an ideal coating for mold release and corrosion resistance applications. It is a MidPhosphorus Electroless Nickel coating that is sprayed with a Fluorocarbon PTFE that is then baked into the pore structure of the Electroless Nickel giving exceptional release properties.
