Dosage Information
  • Can be directly added to the solution to be treated, without any pre-mix or neutralization step.

Indicative use dosages (% of total end-solution weight)

  • Degreasers/Detergents : 0,5 to 1%, depending on the solution pH-range.
  • Temporary protection : 4 to 10% depending on the desired protection period.

When used for temporary protection only, Ascotran® NS should be diluted in soft water and applied onto metal substrates :

  • by dipping
  • by spraying (depending on the spray pressure, a defoamer can be recommended)
  • by brushing.
