PITTSBURGH, May 14, 2001 - Sybron Chemicals Inc., a Bayer Corporation subsidiary, has announced that it is now able to market Lewatit® MonoPlus™ uniform-particle size ion exchange resins in the United States.

As a Bayer subsidiary, Sybron will market these and other Bayer ion exchange resins in the North American region. Bayer AG, Bayer Corporation's Germany-based parent, will offer many of the Sybron ion exchange products worldwide. Bayer Corporation will continue to market ion exchange resins in North America along with Sybron products.

During tests in facilities worldwide, MonoPlus™ resins have demonstrated numerous benefits. The uniform-particle size helps promote maximum kinetic and hydraulic resin performance, according to Phil Fatula, Manager of the Industrial Water business segment. "That means higher throughput per cycle, lower water and chemical consumption and higher mechanical and chemical stability," Fatula said. "Other benefits include longer life cycles, better backwashing properties and easier separation in mixed beds."

Bayer AG's state-of-the-art plant in Bitterfeld, Germany, makes Bayer the world's largest producer of monodispersed ion exchange resins.

Sybron's product range forges the global strength of Bayer's Lewatit ion exchange resins in both industrial water and chemical processing markets with the firm position that its Ionac® ion exchange resins enjoy in the U.S. domestic and industrial markets.
