CINCINNATI – Pilot Chemical Co., Cincinnati, has acquired Mason Chemical Co., Arlington Heights, IL. Together, the companies represent more than 100 years of privately held businesses in the United States.

“Both Pilot, established in 1952, and Mason, founded in 1968, are successful companies built by their respective founders’ families over many decades,” said Paul Morrisroe, Chairman and CEO of Pilot Chemical Co. “The Pilot and Mason product lines are complementary and will allow us to build on synergies between the two companies. Customers of both companies will be better served through a more complete and expanded global product offering from Pilot.”

Mason Chemical Co. develops, registers and sells quaternary ammonium compounds and related chemistries. The acquisition enhances Pilot Chemical's household, industrial and institutional, personal care, and oil and gas product portfolios by adding registered and non-registered biocidal quats and tertiary amine derivatives.
