Coating End Applications
Product Application
  • ASCOTRUST® X3 is added to waterborne coatings directly applied on rusted or poor-prepared ferrous substrates. It ensures an effective blocking effect on residual rust, and avoids its migration through the fresh paint film.
  • Its passivation properties on rust allow to maintain good anticorrosion performances of the coatings, despite the adverse substrate conditions.
  • It doesn’t compromise the coating anticorrosion performance on non-rusted substrates.
  • ASCOTRUST® X3 is mainly designed for waterborne white or colored pigmented coatings, based on various binder technologies: acrylic, alkyd, epoxy, PU.
  • It is recommended to use an organic-type anticorrosion agent when ASCOTRUST® X3 is added to a metal paint formulation.
Dosage

ASCOTRUST® X3 is preferably added at the last manufacturing step (post-addition).

  • In 2K PU systems: should be added into the resin part.
  • In 2K Epoxy systems: preliminary tests should be performed to determine in which part ASCOTRUST-X3 should be added.

Indicative use dosages (% of total coating weight) :

  • 1 to 3% depending on the coating formulation. The dosage can reach 5% into primers or one coat systems, applied on highly reactive rusted substrates, at low DFT (<40-50 μm). It is advisable to determine the optimum amount by a laboratory test.
