The company was established in 1926 on its current site by Mr. James M. Brown to manufacture zinc oxide. At that time the principal use of this material was in paints, rather than rubber as is the case today.

During the 1930s various cadmium compounds were also produced and amongst these were cadmium pigments. The growth of the plastic industry led to greatly increased demand for these pigments, with their unique combination of bright colours, excellent heat resistance and complete compatibility.

In 1945, James M. Brown sold half of his interest to the Tennant group of companies but he continued to run the company until he retired in 1954, when the company became wholly owned by Tennants.

Customers who were buying cadmium pigments for use in plastics were often also using metallic stearates as dispersing and lubricating agents. JMB therefore started to produce calcium, zinc and magnesium stearates so as to broaden the service it could offer.

In July 2000 the company was appointed as agents by Cabot Corporation for the sale of their speciality carbon blacks to the plastics industry. In 2005 this arrangement was extended to include all market sectors.

In 2005, James M. Brown became the sole agent in the UK and Eire for the wide range of products manufactured by Heubach in Germany and India.

In October 2007, James M. Brown acquired Multicel Pigmentos a company located in Sao Paulo Brazil, becoming the world largest producer of cadmium pigments with manufacturing sites in both England and Brazil. www.multicel.com.br
