Black Pigment Production

  • LANXESS increases black pigment capacity
  • Debottlenecking at the world’s largest plant for synthetic iron oxide pigments

As a leading supplier we have expanded the capacity for black synthetic iron oxide pigments at our Krefeld-Uerdingen site by more than 5,000 metric tons per year. The increased demand from the construction industry, in particular for our unique black pigments to color concrete, can be even better met with the debottlenecking measures that have now been completed.Thus, we are continuing the systematic expansion of our production capacities for synthetic iron oxide pigments. LANXESS is the only supplier worldwide to produce these pigments using the Laux process.

In architecture and landscaping, the black coloration of concrete has been a trend for some time now. Concrete is a creative material, which provides a multitude of possibilities to building material producers, architects, and building contractors. With the use of suitable pigments, this applies not only to the architectural design of concrete, but especially to its coloration. Thanks to their up to 15 percent higher tinting strength and reliable color consistency, our Bayferrox 330 and Bayferrox 340 black pigments are the preferred choice for coloring high-quality cement-based building materials – for example not only in manufacturing concrete paving stones and roof tiles, but also in architecture.
LANXESS

In Krefeld, LANXESS operates the world’s largest plant for manufacturing synthetic iron oxide pigments. The global importance of this site is confirmed every year by its extensive investment in capacity expansion and process optimization, as well as the continuous expansion of environmentally friendly production technologies. Thanks to the unique Laux process, the production facility at the Krefeld-Uerdingen site already has an excellent carbon footprint. This is because this special chemical process uses the heat generated during the reaction to create steam, which is in turn used in the subsequent process steps.
