Extreme‑Pressure Additive
Extreme‑Pressure Additive
Extreme‑Pressure Additive is high‑activity sulfur‑based additive for heavy‑load metal‑working fluids. It can form robust protective tribo‑film under high pressure contact, effectively preventing metal seizure and welding.
It shows good solubility in mineral base oils, and exhibits good synergistic effect with anti‑wear agents and rust inhibitors. Widely used in heavy‑duty cutting oil, stamping oil and forming oil formulations for ferrous metal machining.
