Lanxess Lifts Black Pigment Output at Krefeld
Through debottlenecking, German specialty chemicals producer Lanxess has added more than 5,000 t/y of capacity for its black synthetic iron oxide pigments at its Krefeld-Uerdingen site, which it claims as the world’s largest plant for manufacturing synthetic iron oxide pigments. The company said it is responding to increased demand from the construction industry, especially for products to color concrete.
