In industry, hypophosphorous acid is often used for the treatment of metal surfaces. It can be used as a pre-treatment to prevent rust, clean or protect against corrosion of metallic surfaces. It can also increase the adhesion of metal coatings.
It can be a component used in electroplating (electro galvanizing) processes. This process is the application of another metal layer on a metal object by an electrochemical reaction.
Hypophosphorous acid can also be used in polymer production. It can act as a catalyst or reagent in the synthesis of some polymers.
In addition, hypophosphorous acid can be used in some laboratory applications or research studies.
