The NP3 coating is applied through an electroless nickel plating process combined with a fluoropolymer, which gives it its unique properties. The fluoropolymer component helps to reduce friction, which can improve the performance and longevity of the coated parts. This makes NP3 particularly popular for use in firearms, where its low friction and resistance to corrosion and fouling are highly valued.
