ControFil 2 - Corrosion protection

Corrosion protection for wire cutting machines

ControFil 2 was developed for wire erosion machines to prevent the undesirable corrosion of work pieces and machines. ControFil 2 is added to the deionized water. We recommend that ControFil 2 is added to the deionized water in a container outside the machine and then divided equally between the dirty water and clean water tanks. A concentration of 0,5% guarantees optimal rust proofing.

Advantages for the use of ControFil 2:

  • No alteration of the conducting capacity of the deionized water
  • No reduction of the cutting efficiency of the machine
  • Low concentration (0.5 vol.%)
  • Physiological safety
  • Almost odourless
  • No interference with waste disposal
  • No influence on steel, non-ferrous or heavy metal and graphite
  • The processed parts can be further processed without any problems
  • ControFil 2 can be removed with water
  • Filtration of the deionized water is not influenced
  • The concentration of ControFil 2 can easily be checked with a refractometer, (factor 1.5)

If permanent rust proofing of the work pieces taken out of the machine is desired, we recommend aftertreatment with our ControXid products.

ControFil 2 is not suited for precoated filter systems.
