- Dosage
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.
- Function
ASCOTRUST® X2 is a liquid additive for waterborne coatings. Reacts with metal cations to form stable organic complexes chemically bonded on the metal substrates, providing a stable and effective chemical passivation.

- Storage Condition
Ideal temperature conditions: 0 to 30°C. Expiration : 1 year in its original closed drum, in storage conditions described above. Some cristals may form when ASCOTRUST is stored at temperatures below 0°C for several days. Product will recover its initial properties after warming at ambient temperature.
- Application
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... It is recommended to use an organic-type anticorrosion agent when ASCOTRUST-X2 is added to a metal clear-coating formulation.
