DORMAGEN, Germany (May 13)—Bayer A.G. will invest $149 million over the next 12 to 15 months to expand capacity for polyurethane intermediate toluene diamine at its Dormagen site. The new facility will have about 200,000 metric tons of annual capacity for TDA, which is a precursor for toluene diisocyanate; Bayer did not say what the existing capacity is at the site. Bayer will use a newly developed, more cost-effective process at the new facility. The process already is in use at Bayer's Baytown, Texas, site. Start-up is set for the second half of 2003, Bayer said. The new plant will supply Bayer TDI facilities in Leverkusen and Brunsbettel, Germany.
