Dow, Metso units to develop paper coating process

MIDLAND, Mich. (Oct. 14)—The Emulsion Polymers business unit of Dow Chemical Co. and Metso Paper Inc., a division of Metso Corp., have agreed to develop and market a new paper- and board-coating process. Dow will develop the coating chemicals and colors, while Metso will focus on the coating station technology, including supply systems, drying and process automation. The new process, based on a patent-pending multilayer curtain coating application, is significant because several coating color layers can be applied at the same time to the paper web without any direct mechanical contact, according to Ted Cosse, Dow Emulsion Polymers vice president.
