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.
Lockhart is a global leader in gelled calcium sulfonates. These are the basic building blocks for formulating very long-term, self-healing permanent coatings as well as calcium greases. Gelled calcium sulfonates are available in oil-based, solvent based semi-finished coatings, water-based semi-finished coatings and vegetable based. Gelled calcium sulfonates are useful in formulating ballast tank coating for ships, automotive underbody coatings, VGP and eco-friendly compliant lubricants, seams sealants and cavity waxes, rheology modification and providing additional rust prevention in paints.
Lockhart is a global leader in the manufacturing of basic oxidates, esters and soaps, including their application and benefits.
Lockhart Chemical Company is a producer of effective base oil emulsifier packages for functional fluids. Emulsifier packages can often provide cost savings and flexibility in formulation of soluble oils for metalworking fluids.Lockhart is basic in all major components of emulsifier packages including sulfonate and non-sulfonate primary and proprietary secondary emulsifiers. Inquire about custom packages to emulsify your specific base oil.
In addition to Sulfonates, Base Oil Emulsifiers, Corrosion Inhibitors, and Rust Preventives, Lockhart Chemical manufactures a wide range of metalworking fluid additives including amides, co-emulsifiers, lubricity and extreme pressure additives.
Counter Rust Barium Sulfonates are manufactured to Lockhart’s exact specifications at it’s Flint, Michigan facility offering customers a secure source of supply. Versatile Barium Sulfonates are useful in a wide range of applications where water dispersion and rust prevention are important.
