Superior Metal Deactivator for Optimal Lubrication & Protection
A metal deactivator (passivator) is a critical lubricant additive that neutralizes metal-catalyzed oxidation & corrosion, delivering longer oil life, better equipment protection, and stable lubrication
Core Mechanisms
Film Formation: Creates a dense inert barrier on metal (especially copper/alloys) to block active sulfur, acids, and radicals
Chelation: Binds metal ions (Cu²⁺, Fe³⁺) into stable complexes, eliminating their catalytic oxidation effect
.
Synergy: Works with antioxidants (e.g., Irganox) to boost oxidative stability
.
Top-Performing Types
Benzotriazole (BTA) / Tolyltriazole (TTA) Derivatives
Oil-soluble, ashless, low-dose (0.01–0.05%)
.
Salen-Type Complexes
For aviation/jet fuels; neutralizes trace copper (0.1 ppm+).
Key Benefits
✅ Extend oil drain intervals✅ Prevent copper blackening & corrosion✅ Reduce sludge/varnish✅ Lower maintenance costs✅ Compatible with most lubricant additives
Typical Applications
Engine oils, gear oils, hydraulic fluids
Turbine oils, transformer oils, metalworking fluids
Greases, aviation fuels
