The global building chemicals and materials supplier W. R. Grace & Co. has completed its separation into two independent, publicly traded companies: W. R. Grace & Co. and GCP Applied Technologies Inc. This comes a year after Grace first announced its plans to divide. Grace previously operated in three segments: Grace Catalysts Technologies, Grace Materials Technologies and Grace Construction Products (GCP). From now on, Grace will continue to own and operate the company’s existing Catalysts Technologies and Materials Technologies segments, according to the company. The Darex Packaging business will become a part of GCP. Grace will continue to process catalysts and specialty silicas. The company expects to have sales of approximately $1.8-billion. The GCP portfolio includes concrete admixtures, fibers, surface treatments, and liquid pigments; additives for cement processing; and fire-protection, waterproofing and masonry products. Post separation, Grace believes GCP will have sales of approximately $1.5-billion. Following the announcement, Grace named Hudson La Force (pictured) president and CEO effective immediately. He joined Grace in 2008, and succeeds current chairman and CEO Fred Festa. Greg Poling leads GCP as president and CEO.
