LANXESS at the European Coatings Show 2005, Nuremberg, April 26 – 28, Hall 4, Stand 645

LEVERKUSEN -- Powder coatings differ substantially from liquid coatings with respect to both production and application. Particular care is required when choosing pigments due to differences in manufacturing methods and film formation, and also because of the high baking temperatures required for powder coatings. Otherwise problems can occur with dispersibility, shade adjustment, leveling and color stability during baking. The properties of Bayferrox® High Performance and Colortherm® pigments from LANXESS Deutschland GmbH make them particularly well-suited for use in powder coatings. The consistent quality of these heat-stable pigments means reliable production, especially in this application. LANXESS will be exhibiting its comprehensive range of pigments for the coatings industry at the European Coatings Show 2005 in Nuremberg, Germany.

The Bayferrox® line includes red, yellow, black and brown pigments. These iron oxides are generally characterized by maximum weather resistance and lightfastness, and can be combined with suitable binders to formulate durable coatings.

With their high scattering power and good tinting strength, the red pigments impart excellent hiding power to coating films. These properties together with very high heat resistance ensure the greatest possible color consistency, even at high baking temperatures.

Colortherm® 10 and Colortherm® 20, iron oxide yellow pigments that have been stabilized by post-treatment with inorganic substances, have been specially developed for higher temperatures. Additionally, the yellow pigments Colortherm® 30 and Colortherm® 3950 are available for temperatures above 200 °C.

The black pigments of the Bayferrox® product line may not be quite as heat resistant as these yellow pigment grades, but their thermal stability is still sufficient for many powder coatings. The heat resistance of Bayferrox® 303 T, on the other hand, makes it suitable for use in nearly any binder system without risk of color shifts during baking, as it remains stable up to 600 °C.

Bayferrox® 645 T is a heat-stable brown pigment that meets the most stringent requirements. Rather than a mixture of iron oxide components, it is a monophase pigment derived crystallographically from the structure of bixbyite.

Similar to the red Bayferrox® pigments, micronized Chrome Oxide Green GN-M is characterized by its extreme resistance to heat and high scattering power, which make it particularly well-suited for use in powder coatings.
