Chemfac PC-188

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 Chemfacs also exhibit corrosion inhibiting properties when neutralized with amines. Chemfac PC-099E is recommended primarily for synthetic and semi-synthetic formulations. Chemfac PC-188 is recommended primarily for straight oils, soluble oils and semi-synthetics.
