Using its leadership position in oxidates, sulfonates, and proprietary chemistry, Lockhart has developed a wide range of high performance rust preventives and corrosion inhibitors. Lockhart rust preventive packages form physical and chemical barriers to metal surfaces through oxidate, esters, waxes, and sulfonate technologies. Lockhart’s water soluble corrosion inhibitors are based on a wide range of acids bases allowing the formulator flexibility to achieve the desired performance and cost. Lockhart’s surface protection laboratories offers comparative testing, ASTM tests for corrosion and rust protection including stability, salt spray, humidity, stack/stain, demulsification and dewatering and corrosion.
