The price increases are driven by increased basic raw material costs, tightening availability of some key raw materials and rising freight costs. Nalco's sales engineers will discuss the specific impacts of these increases with individual customers.

"Long-term upward price pressure on key raw materials is making it necessary for the Colloidal Technologies Group to implement appropriate price increases to help offset these continuing cost headwinds," said Joe Kosiek Strategic Business Manager, Colloidal Technologies Group. "By taking this necessary action, we can continue to invest in research, manufacturing process improvements and development of our people that enable us to provide sustainable solutions and value for our customers."

The Colloidal Technologies Group manufactures colloidal silica, specialty sols and complementary process chemicals used in various industries including precision investment casting of metal parts, polishing of silicon wafers, memory disks and other electronic substrates, vacuum-formed shapes and high-temperature refractories, catalyst supports, wine and juice clarification and specialty coatings.
