Sodium Hypophosphite application:
Sodium Hypophosphite (SHP) acts as a reducing agent to supply the electrons necessary
for the Electroless Nickel process. The EN process allows for uniform plating thickness on
not only metal objects, but also plastics and ceramics.SHP may be used as a reducing agent
or antioxidant in chemical processing, also may be used as a partial fire retardant.
