Wacker Chemie AG will discontinue the production of its PIOLOFORM® polymer binders effective September 30, 2008. The Munich-based chemical group announced this decision today, citing limited expectations for polyvinyl butyral growth in industrial applications such as coatings, paints and printing ink. At the same time, raw material and energy costs continue to climb sharply. Both these factors are putting at risk the sustained profitability of this business.
