ALTANA Enters Agreement to Acquire Rheology Modifier Business from Rockwood


Expansion of highly specialized additives business

ALTANA has signed a definite agreement to acquire the global rheology business of Rockwood Holdings Inc. The unit, currently part of Rockwood’s Performance Additives segment, is one of the world’s leading manufacturers of rheology additives that optimize the flow characteristics of various materials. With about 340 employees at four production sites in the U.S., the UK and Germany the rheology business generated sales of $191 million in 2012. After approval by the relevant antitrust authorities, ALTANA will integrate the business into its BYK Additives & Instruments division.

The purchase price amounts to $635 million. The closing of the transaction is expected to take place in the fourth quarter of 2013. With the acquisition ALTANA is expanding its existing additives portfolio.

“The acquisition of Rockwood’s rheology business is fully in line with our focus on true specialty chemicals and opens up new growth opportunities,” ALTANA CEO Dr. Matthias L. Wolfgruber said. “By acquiring Rockwood’s rheology business, we are further enhancing our financial profile and are creating long-term value.”

Rheology additives are amongst others used in coatings, construction materials and personal care products. They can, for example, ensure that coatings have the right viscosity and that they can be applied without forming droplets or bubbles.

“The acquisition is associated with an attractive growth potential,” Dr. Christoph Schlünken, president Division BYK Additives & Instruments, said. “We will, for example, use the existing BYK structure to grow the acquired rheology business in Asia.”

With the acquisition ALTANA’s sales are expected to reach about EUR 1.9 billion. There will be four additional production sites: Gonzales (Texas), Louisville (Kentucky), Widnes (UK) and Moosburg (Germany). The number of employees will rise to about 5,700.

In 2012, ALTANA achieved sales of more than EUR 1.7 billion. With its high profitability and dynamic growth ALTANA is one of the most successful and innovative chemical groups worldwide.
