Curtain coater installed at BASF’s pilot plant
trials by customers in the graphic and packaging sectors. It is suitable for coating colours on paper and board. Because of the contact-free
A
technique, the curtain coater – based on a Voith DF Coat slot dye machine – allows a particularly homogeneous and defect-free contour coating layer to be applied. BASF says that during the coating process, the base paper undergoes no mechanical stress, and as a result, runnability
curtain coater has been installed at BASF’s pilot plant at Ludwigshafen for use in application
through the curtain coater is enhanced. In addition, highly uniform fibre coverage and layer thickness are achieved, which not only have a positive effect on printability and optical effects, but also can give paper very good barrier properties. In addition to the newly-installed
curtain coater, BASF continues to offer all industry standard coating application methods on its state- of-the-art paper coating machine, including roll / blade, jet / blade, roll / varibar and film press. Coating colours can be produced on site. All necessary preparation facilities are available, including
options for dispersing pigments at variable shear and preparing starch solutions with both batch and jet cookers. A 12-roll super calender enhances sheet smoothness and gloss development. The paper produced can be cut, packaged and shipped as required. BASF says the investment in the curtain coater underlines its ongoing commitment to the paper and board industry, especially in the areas of packaging and barrier applications. The combination of an extensive product portfolio, a paper-specific testing laboratory and experienced and qualified employees reinforces BASF’s
market position as a leading supplier of paper coating chemicals. “With the installation of the
new curtain coater in our pilot plant, we are completing our range of application technologies and can thus further advance the optimization and development of coating formulations together with our customers,” says Professor Thomas Schiele, vice president of BASF’s Paper Coating Chemicals Europe. “This will further strengthen our application expertise in the field of paper coating chemicals at our Ludwigshafen site.”
