Bayer Corp., Pittsburgh, announced plans to close one production line for synthetic iron oxide pigments at the company's New Martinsville, WV, manufacturing site. The line, which produces standard-grade iron oxide pigments, will be closed in early 2002. The company said it will continue to produce iron-oxide and zinc-ferrite pigments at the plant, with those grades focused primarily on high-performance paint and plastics products. Standard-grade iron-oxide products will be supplied from other Bayer sites, the company said. The action is part of a global cost-reduction program for Bayer's Coatings and Colorants business group.
