Lockhart Chemical Company roots go back to the late 1800’s when Charles Lockhart entered Pennsylvania’s oil industry. After nearly a century in the steel and aluminum business, in 1982, The Lockhart Company purchased a 13 acre chemical manufacturing site in Michigan which became Lockhart Chemical Company. Today, Lockhart manufactures and globally markets a wide range of additives for formulating rust preventives, corrosion inhibitors, emulsifier packages and other processing additives for metalworking and greases.
