DOVERPHOS EP-425 is a polymeric phosphite ester suitable for machining/grinding of ferrous and non-ferrous alloys. Can be incorporated in neat oils, as well as water–dilutible coolants.
DOVERPHOS EP-425 brings both anti-wear (AW) and extreme pressure (EP) to the compounder/blender’s formula.
Advantages and Benefits:
Light color and low odor
Non-chlorinated extreme pressure lubrication extends tool life and improves finishes
Stable in a wide variety of mineral oils, synthetic oils, and esters
Extremely low acidity, thus reducing possibility of staining on non-ferrous alloys
30% wear scar reduction compared to inactive sulphurised ester
30-40% wear scar reduction compared to other phosphorus-containing additives
Higher efficiency in drawing carbon steel and stainless steel compared to sulphurised additives, chlorinated additives, and other phosphorus-containing additives
Equal performance to chlorinated, and sulphurised additives in tapping carbon steel
