OX-401 ; Acid zinc plating intermediate ; low-foam anionic surfactant ; a carrier for acid zinc plating
OX-401 is a low-foam anionic surfactant, a carrier for acid zinc plating, and can also be used for acid zinc-nickel alloy and acid copper plating. It has good salt resistance, good throwing ability, high current efficiency, and excellent hydrolysis resistance. It has good dispersion and emulsification in acid zinc baths of different concentrations, and has excellent overall performance. OX-401 is suitable for barrel plating and rack plating.
