ISOCONTRAN is recommended for grinding tools made of sintered tungsten carbide, where cobalt is used as a binder. Its synthetic formula includes a special additive package to prevent the leaching of cobalt by the coolant. It also contains polymer lubricant additives to extend the life of grinding wheels and to prevent dry residues on machines.

A minimum concentration of 5% is recommended.

Usage Recommendation

Grinding of sintered tungsten carbide: 5-10%


  • Completely repels foreign oil: excellent workpiece visibility without coolant loss
  • Inhibits cobalt leaching: reduces risk for workers and the environment
  • Exceptionally low foaming: no need for foam inhibitors
  • Excellent cleaning power: cleaner workpieces, machine tools, and work environment
  • Contains polymeric lubricity additives: longer wheel life and prevention of residue accumulation on machines
  • Rapid fine material separation: excellent filterability with extended filter life
  • Free of Boron: no SVHC classification under REACH
  • Excellent EHS profile (Environment, Health, Safety): Free from mineral oil, boron, chlorine, secondary amines (TRGS 611), formaldehyde, and phenol
