Red Lead

Red Lead (Pb304 or 2PbO, PbO2) is soft orange and red colored powder. It is a useful ingredient for the storage battery, glass & ceramic industry and it occupies an important place in the Paint Industry for its rust inhibiting character. It is virtually insoluble in water and alcohol. However, it is soluble in the hydrochloric acid present in the stomach, therefore it is toxic when ingested. It dissolves in hydrochloric acid, glacial acetic acid, and a diluted mixture of nitric acid and hydrogen peroxide.

Red Lead


Red Lead is used to a certain extent in the ceramics and glass, paints and pigments and explosives industries.Our Red Lead Non-Setting is a highly superior quality product and is the market leader.

S S International also produces Red Lead Ordinary conforming to IS :57-1989 Type A and B. This formula corresponds to a PbO2 content significantly lower than 34.0% dependent upon the particular application in which they are to be used.
