One Equity Buying Columbian Chemicals from DC Chemical

One Equity Partners has agreed to acquire the remaining 66.75% stake in Columbian Chemicals Holding LLC that it does not already own, for $150 million. The seller is South Korea-based DC Chemical Co., which partnered with One Equity to buy Columbian Chemicals in 2006 for $600 million from Phelps Dodge Corp.


Columbian Chemicals is a Marietta, Ga.-based maker of carbon black, a material used to increase durability in products like tires and plastics.


Dechert LLP is advising One Equity on the deal, which is expected to close later this quarter.
