Industrial water used to blend aqueous metalworking fluids contains a number of cations which increase in concentration as water evaporates. CUBLEN sequesters ions that would otherwise form soaps on equipment or work pieces and helps to maintain emulsion stability. The phosphorus content of this multifunctional chelating agent also provides corrosion inhibition and antiwear protection.

Z&S manufactures a variety of phosphonate chelating agents and stabilizers that extend metalworking fluid life, and also provide an additional EP/AW boost. Metalworking fluids formulated with CUBLEN chelating agents will keep the metalworking fluid sump clean. Z&S metalworking fluid additives are used in water-based fluids for metal removal and metal forming operations including cutting, drilling, grinding, milling, rolling, stamping, and forging applications.
