Sodium hypophosphite is mainly used for electroless nickel plating. With this method, a durable nickel-phosphorus film can coat objects with irregular surfaces, and can widely be in avionics, aviation and the petroleum field.
Sodium hypophosphite is capable of reducing nickel ions in solution to metallic nickel on metal substrates as well as on plastic substrates.The latter requires that the substrate is activated with fine particles of palladium. The resulting nickel deposit contains up to 15% phosphorus.
Any question about SHPP or electroless plating, you can ask me.
