High-performance metal deactivator specifically designed for copper and its alloys.
Excellent thermal and oxidative stability in hydrocarbon-based systems.
Low volatility and good compatibility with mineral oils, synthetic lubricants, and fuel formulations.
Effective at low treat rates (typically 10–100 ppm), minimizing formulation impact.
Non-corrosive to common metals and compatible with other additive packages including antioxidants and detergents.
Turbine oils and circulating systems requiring long-term copper passivation.
Internal combustion engine oils where copper-bearing components (e.g., bearings, bushings) are present.
Transformer oils and insulating fluids to suppress copper-catalyzed oxidation.
Gasoline and diesel fuels containing copper-containing fuel system components.
