Causes of Foam in Metalworking Fluids

Foam in metalworking fluids has two primary causes, system design factors and the additives that make up the formula. Examples of these causes are:

  • System Design Factors
    • Small sump pumps
      • Insufficient capacity to allow foam to break quickly enough
    • High application pressures
  • Formula Additives
    • Ethoxylated surfactants
    • Fatty acid amides
    • Amine neutralized carboxylates
    • Petroleum sulphonates
    • Other surfactants
