457Iron Oxide Pigments By Cynthia T. Collins1 Production and trade in finished iron oxide pigments were up in 1978, owing to continued strong demand for pigments in building materials, industrial coatings, and commercial paints. A decline in the construction and automotive industries in 1979 resulted in lower demand for pigments. Total U.S. production for the year increased, however, owing to the first full year of production by Mobay Chemical Corp. The first stage of Mobay's new synthetic iron oxide pigment plant at New Martinsville, W. Va., was completed in the third quarter of 1978. Production began late in the year, and shipments started early in 1979. The final stage of the 45,000-ton-per-year capacity plant was scheduled for completion late in 1980. Early in 1979, Pfizer Inc. completed an expansion at its Easton, Pa., plant where production capacity for copperas red pigment was increased by 25%. Cities Service Co. formed a new subsidiary, Columbian Chemicals Co., in 1979. Production and sales of iron oxide pigments are now functions of the latter company. Capacity of the Columbian Chemicals plant at Monmouth Junction, N.J., was expanded by 20% in 1979. Chemetron Corp., a wholly owned subsidiary of Allegheny Ludlum Industries Inc., sold its Pigments Division to BASF Wyandotte Corp., the U.S. branch of the BASF AG Group of the Federal Republic of Germany. The transaction included the synthetic iron oxide pigment plant at Huntington, W. Va. In 1978 Mineral Pigments Corp. phased out production of natural iron oxide pigments made from raw materials. The company now markets only blends made from purchased pigments. In December 1978, the Dry Color Manufacturèrs' Association established a committee of iron oxide pigment producers to conduct a literature search on the safety of iron oxide. The committee intends to issue a position paper for the industry and provide documentation that iron oxide is not a carcinogen.
