W.R. Grace & Co. has agreed to acquire the Fine Chemistry Services (FCS) business of its fellow US speciality chemicals company, Albemarle, in a deal that is expected to close in Q2, subject to regulatory approvals and other customary conditions. This will bring Grace sites at Tyrone, Pennsylvania, and South Haven, Michigan. FCS will fit within Pharma & Consumer, which Grace described as “the largest, fastest growing and most profitable sub-segment” in its Materials Technologies business.
