Lanxess Inorganic Pigments
The Inorganic Pigments business unit is one of the world’s leading manufacturers of inorganic pigments, with a broad and innovative product range and acknowledged expertise in technical service. The business unit has a global presence with production facilities in Germany, China, and Brazil as well as with additional mixing and milling facilities in Australia, the UK, Spain and the United States. Iron oxide and chrome oxide pigments from the LANXESS Inorganic Pigments are distinguished by their high quality and simple, standards-compliant and environmentally compatible processing.
Marketed under the names Bayferrox®*, Colortherm®* and Bayoxide®*, the business unit’s iron oxide and chrome oxide pigments have become the standard worldwide. They are characterized by their outstanding lightfastness, weather stability and chemical resistance.Bayferrox®* synthetic iron oxides are available as powder, micronized powder, granules and compact pigment. These microgranules are particularly low-dusting and have a much higher bulk density than a corresponding powder, which represents a major advantage for transport and storage.

Bayferrox® and Colortherm® colour pigments.
LANXESS inorganic colour pigments marketed under the product brands Bayferrox® and Colortherm® are available in Red, Yellow, Green, Brown and Black. In between these colours a wide variety of additional shades are possible. In total LANXESS offers more than 100 different colour shades for various fields of application.
The Bayferrox® product range is based on iron oxide pigments. Within the Colortherm® product range, the red, yellow, brown and black pigments are also based on iron oxides. However, there are also Colortherm® Green products which are based on chrome oxide pigments.
Synthetically produced inorganic colour pigments are available in different delivery forms: powder, micronized powder, granules and compacted pigments. All products are recognized for their outstanding colour stability, excellent light fastness, weather stability and chemical resistance.
Powder pigments are mainly used in the colouring of various construction materials. Due to the chemical composition and structure of these pigments, they are insoluble in water and diluted acids, resistant to cement, lime and alkaline and totally weather and light stable.
These pigments fulfil the special requirements needed particularly in the paint and coating industry. Through micronization, an intense milling process, the level of pigment agglomerates is significantly reduced. As a result, these pigment grades exhibit high dispersibility.
Bayferrox® C is a grainy material which is nearly dustless and shows good free flowing properties. Bayferrox® C can be used in a wide range of concrete applications and gives a good price versus performance ratio. The product properties of this modern delivery form were designed especially for the colouring of concrete materials.
Bayferrox® G pigment granules are the result of a special manufacturing process. Pigment granules offered under the name of Bayferrox® G are free-flowing which allows them to be easily discharged from silos, paper bags and bulk bags. As a result of their dust free nature, storage and metering are clean.
With Bayferrox® 350 FL LANXESS offer a liquid variant from the Bayferrox® product range. Bayferrox® 350 FL is an aqueous iron oxide black suspension specifically manufactured for the colouring of concrete goods. In addition to the well-known product properties of the Bayferrox® pigment range, Bayferrox® 350 FL also offers the advantage of dust-free and clean metering.
Bayoxide® for technical applications.
For special applications LANXESS supplies a comprehensive range of Bayoxide® products. The Bayoxide® product range is divided into Bayoxide® E pigments that are produced based on iron oxides and the Bayoxide® C pigments manufactured based on chrome oxides. Similar to the LANXESS colour pigments also the technical oxides have a certain colour (Red, Yellow, Green and Black). However, compared with the chemical and physical properties, the colour plays only a minor role.
All Bayoxide® products are often particularly developed for different markets, Industries and requirements. This range encompasses products used for the manufacture of airbags, brake linings and refractory ceramics, pigments for toners used in photocopiers and laser printers and adsorbers for drinking and waste water purification.
