Dosage

Can be added at any manufacturing step. Can be post-added. In 2K systems: should be added into the resin part in most cases (to be checked with preliminary testing). Indicative use dosages (% of total coating weight) :

  • 0.3 to 0.6% on degreased steel, not rusted, sand- blasted or not.
  • 0.5 to 1.5% on cast-iron or rusted substrates.
  • 0.3 to 1.5% for packaging protection.

Above dosages can be increased when the coating is applied in severe conditions of ambient humidity.
