ALOX® 2165 Rust Preventive

ALOX® 2165 rust preventive provides exceptional protection against rust and staining, making it ideal for stacked or coiled steel and storage applications.

ALOX 2165 Rust PreventiveALOX 2165 calcium package offers exceptional thin film rust protection using a formulation that is free of barium and heavy metals. This rust preventive is soluble in solvent, solvent/oil, and oil diluents to meet a full range of treat rate and performance requirements, and provides over 72 hours of rust protection as measured by the ASTM B117 salt spray test.

ALOX 2165 rust preventive offers unique solubility characteristics with excellent water separation and water displacement, ensuring film consistency in dip tank applications. It is also non-staining, so treated metals can be stacked or coiled without blemish.

Recommended Applications

  • Slushing oils
  • Protective storage and shipping fluids
  • Dip tank fluids
