Multi-metal corrosion inhibitor for metal working fluids

Hostacor AL

Hostacor AL is a phosphorous-free, water-dispersible corrosion inhibitor based on 100% renewable feedstocks recommended for steel-and aluminum cutting & grinding emulsions. The product has a low foaming tendency and contributes significantly to lubrication while at the same time reduces cobalt leaching.

Hostacor AL can also be added to existing metal working fluids for steel to upgrade them for machining aluminum.

  • Hard water stable, no formation of lime soaps
  • Outstanding corrosion protection of steel
  • Excellent inhibition of corrosion and staining on aluminum
  • Forms a protective layer on aluminum surfaces
  • Existing metal working fluids for steel can be upgraded by adding Hostacor AL for machining aluminum
  • Minimizes cobalt leaching
  • Low foaming tendency
  • Significant contribution to lubrication
  • Free of phosphorous (does not support growth of microorganisms)
