Sodium Hypophosphite, commonly referred to as SHP and sodium phosphinate, is an inorganic hypophosphite salt used as a reducing agent in electroless nickel plating processes. It functions by undergoing controlled oxidation to supply electrons for the autocatalytic deposition of nickel from aqueous plating baths, enabling uniform metal coating without external current, and its performance is closely related to bath composition and operating conditions (CAS 7681-53-0). For industrial supply requirements, the material is provided with competitive factory pricing, customized specifications, complete documentation including MSDS, TDS, COA, and options for bulk supply.

FAQ - Technical & Supply Chain
-
Q:
Do sodium hypophosphite and sodium phosphinate refer to the same substance?
A: Yes. Sodium hypophosphite and sodium phosphinate are alternative names for the same compound and correspond to a single CAS identity. -
Q:
Is sodium hypophosphite primarily used as a reducing agent in industrial plating processes?
A: Sodium hypophosphite is commonly used as a reducing agent in electroless nickel plating systems, where it supports metal deposition through controlled chemical reactions rather than electrical input.
