Dosage Information
  • Ascotrust® X2 is preferably added at the last manufacturing step (post-addition).
  • In 2K systems : should be added into the resin part in most cases.
  • Indicative use dosages (% of total coating weight) : 1 to 3% depending on the coating formulation.
  • The dosage can reach 5% into pigmented coatings applied on highly reactive rusted substrates, at low DFT (<40-50 μm).
  • It is advisable to determine the optimum amount by a laboratory test.
Applications
  • Ascotrust® X2 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® X2 is mainly designed for waterborne clear- coatings based on various binder technologies : acrylic, alkyd, epoxy, PU,etc.
  • It is recommended to use an organic-type anticorrosion agent when Ascotrust® X2 is added to a metal clear-coating formulation.
