Product description:

METAL DEACTIVATOR is a high-efficiency fuel metal passivator used in gasoline and diesel additives to neutralize trace metals such as copper and iron that promote fuel oxidation. It inhibits metal-catalyzed degradation, reduces gum and deposits, and improves fuel storage stability and cleanliness. As a reliable metal deactivator supplier and manufacturer, we offer consistent quality and bulk supply for fuel additive and industrial applications.

Product Applications:

  • Gasoline Additives:Improves gasoline oxidation stability and prevents color deterioration during storage.
  • Diesel Additives:Enhances diesel storage stability by suppressing metal-catalyzed degradation.
  • Fuel Storage & Distribution:Controls trace metal contamination in fuel storage tanks and distribution systems.
  • Additive Packages:Works synergistically with antioxidants to improve overall fuel stability.

Frequently Asked Questions

Metal passivators interact with trace metals such as copper and iron, reducing their catalytic activity and helping slow oxidation reactions that can contribute to fuel degradation.
Yes. It can be incorporated into compatible additive packages containing antioxidants, detergents, cetane improvers, and other fuel-treatment components. Compatibility should be confirmed for the specific formulation.
Key parameters include Sb₂O₅ content, sodium level, pH, specific gravity, viscosity, and appearance according to the required fuel additive specification.
Certain trace metals can catalyze oxidation reactions in fuels, potentially accelerating degradation and contributing to gum, deposits, or changes in fuel quality during storage.
