Applications
NORDOX CUPROUS OXIDE, RED, PAINT GRADE is used to made ship bottom anti-fouling paint (to kill the lower marine plants and animals); it shows excellent effects to inhibit and kill the Myxobacteria, algae, Shelled creatures, waterweeds and other common microbes in water. It is a long acting antifouling agent not only compatible well with the marine paint but also environmental friendliness.
It is also used as a main raw material to produce bactericide in farm chemical industry, or used as red pigment in ceramic, enamel and glass industry.
Furthermore, it can also be used to manufacture various kinds of copper salt or analytical agents, or as a raw material of electroplating rectifier in electrical appliance industry.
