KaiserTech said it reached agreements to sell the rest of its chemicals business to various purchasers, completing the Oakland company's plan to focus on its aluminum operations. KaiserTech already agreed to sell its Harshaw/Filtrol specialty chemicals business. In all, KaiserTech will net about $350 million after assuming some Harshaw/Filtrol debt. The company said it will break even on the divestitures. Under the latest agreements, KaiserTech will sell its industrial chemicals operations based mainly in Louisiana to newly formed LaRoche Chemicals, will sell FarBest Corp. to Diversey Corp. and will sell its brine chemicals operations in Utah to Reilly Tar & Chemical Corp.
