Applications

Chemfac phosphate esters exhibit a variety of properties including emulsification, lubrication, cleaning and wetting. Due to the presence of phosphorous, some of the Chemfac products show excellent extreme pressure (EP) properties in addition to conventional lubricity properties. Certain Chemfac’s also exhibit corrosion inhibiting properties when neutralized with amines.
