By David Reed, UT EditorHerne, Germany-Degussa AG has just started to build its first plant for making dicyclohexylmethane-4,4-diisocyanate (H12MDI), and expects to bring it on stream in the second half of 2005. Carl Voigt, head of the firm’s coatings & advanced fillers division, and Thomas Hermann, head of the coatings & colorants business unit of Düsseldorf-based Degussa, officially opened work on the new plant in Herne on May 18.”This is an important addition to Degussa’s range of aliphatic isocyanates,” a statement from the firm said. Degussa claims to be the world market leader in the production of aliphatic diisocyanates isophorone diisocyanate (IPDI) and its derivatives, and TMDI.The new product, which will be sold under the Vestanat H12MDI tradename, has a cycloaliphatic structure, which yields polyurethanes with very high light- and weather-resistance as well as outstanding mechanical properties and good resistance to hydrolysis and chemicals, Degussa said. Vestanat H12MDI is especially suitable for the production of elastomers, polyurethane dispersions, and radiation-curing urethane acrylates, the firm added. “
