About NP3®

Electroless Nickel with PTFE (EN / PTFE)

NP3 (Electroless Nickel / PTFE) and NP3+ (Electroless Nickel / PTFE with a High Phosphorus Electroless Nickel undercoat) are Durable, self-lubricating Nickel / PTFE composite coatings that can support a wide range of engineering applications. With a 0.1 coefficient of friction and up to 500 hours salt spray resistance this thin, hard and lubricious coating combines a low coefficient of friction with wear resistance, electrical conductivity and increased protection from corrosion. The coatings autocatalytic (electroless) deposit reduces the thickness variations that are associated with electrolytic deposits and creates a thin uniform coating that is accurately deposited across complex geometries.

With 36 years of experience providing the NP3 (EN/PTFE) plating, Coating Technologies is an industry leader. You can trust your EN / PTFE coating requirements to our experienced qualified staff.
