Hercules’ Brunswick Production Facility to Be Expanded

WILMINGTON, DELAWARE, October 24, 2007…Hercules Incorporated announced that as a result of its recent acquisition of the phosphate ester surfactant (PES) business from Dexter Chemicals L.L.C., it will locate PES production at its facility in Brunswick, Georgia. The Brunswick plant, which is part of the Hercules Aqualon Group, will be expanded to accommodate the additional production. The new product line will complement the existing Specialty Resins group of products that became part of Aqualon in late 2006, once again strengthening the role of the Brunswick facility.

“Our Brunswick production facility is integral to Aqualon’s growth,” commented John Panichella, President of Aqualon.  “In addition to the new phosphate ester surfactant business, we are expanding the capacity of wood rosin recovery to support expected growth in our specialty rosin ester business. These products go into key markets including those of Food and Beverages, Construction, Personal Care, and Adhesives. This expansion is a significant investment by Hercules and will strengthen our overall market position for the future.”
