BASF To Sell Hydrophilic Melt Additives Business To Techmer PM

Germany-based chemical company BASF SE has announced it will sell its hydrophilic melt additives
business, including intellectual properties and technical information, to Techmer PM LLC, a
Clinton, Tenn.-based manufacturer of colors and additives for the plastics and fiber industries.
BASF markets the additives under the trademark Irgasurf® HL, which will not be transferred as part
of the transaction. The company reports the sale will not affect its organizational structure.

“In the course of the integration of the former Ciba Plastic Additives business we have
analyzed our combined offering to the plastics industry and have decided that the Irgasurf HL
products do not fit our strategic scope,” said Soeren Hildebrandt, vice president, global strategic
management and new business development, Performance Chemicals, BASF.

“We are excited about the acquisition of BASF’s hydrophilic melt additives business and are
in a unique position to successfully grow this business because it complements our existing product
line and strong presence in the markets of fibers and nonwovens,” said John R. Manuck, president
and CEO, Techmer PM.
