Two new lines of UV-cure and radiation-cure coating binders for plastics were recently unveiled by Bayer MaterialScience’s Coatings, Adhesives and Sealants business unit (U.S. office in Pittsburgh). Products in both lines can also be used for dual-cure applications. Bayhydrol UV is a line of waterborne, UV-curing polyurethane dispersions for wood and plastics coating. The first product is grade XP 2689, which is said to make it possible for the first time to apply a finish to mobile phones without any organic solvents. The product can be used to formulate clear coats and metallic-effect finishes as one-coat systems. The company claims a breakthrough in such a high level of crosslinking for waterborne products. Desmolux coating binders are solvent-free, radiation-curing (UV or electron beam) acrylates. Either rigid or flexible coatings can be formulated. The first grade, XP 2666, is said to be the first allophanate urethane acrylate coating binder, which reportedly produces coatings with high resistance to chemicals, weathering, and mechanical stress.
