Aqueous metalworking lubricants are formulated to provide cooling while protecting tools and delivering good surface finish.  This requires the stable emulsification of hydrophobic base stocks and additives that reduce friction, wear and corrosion.

MULSIFAN polyglycol products are available in a wide variety of HLB values to provide excellent nonionic emulsifying properties in hard and soft water with low foaming tendency.  PURTON amides are emulsifiers that also act as pH buffers and protect against corrosion.

PHOSPHETAL phosphate esters are multifunctional anionic emulsifiers and wetting agents that also provide excellent lubricity, wear protection and corrosion inhibition.

These products can be used alone or in combination to achieve the desired formulation properties.

Metal substrates are subject to rust or oxidative corrosion in the presence of water and aggressive chemicals, and therefore require protection during cutting and forming operations. We offer a variety of phosphorus or nitrogen based additives that bond or adsorb on metal surfaces to protect them against corrosive chemical attack which can cause staining or pitting. Take advantage of the multifunctional performance of Phosphetal phosphates, Cublen phosphonates and Purton amides.

Phosphate esters are multifunctional additives used to formulate aqueous cutting and forming fluids due to their high polarity and affinity for metal surfaces. They act as anionic surfactants that provide wetting and corrosion inhibition. Phosphetalproducts reduce friction between metal-to-metal surfaces during machining, providing wear protection under extreme pressure conditions. Acid phosphate esters are also used in paints, coatings, inks and metal cleaning applications due to their detergent/dispersant functionality. Phosphetal phosphate esters are available in acid form or as neutralized salts.

Aqueous metalworking fluids protect valuable tools from wear induced by high pressure and high temperature contact. Z&S Phosphetal and Cublen additives have high polarity and high phosphorus content which enable them to form protective tribo-films under boundary lubrication conditions. They also act as corrosion inhibitors to protect metal surfaces from oxidative attack.

Industrial water used to blend aqueous metalworking fluids contains a number of cations which grow 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 also provides multifuntional corrosion inhibition and antiwear protection.
