ASCOTRUST® X3
ASCOTRUST® X3 is a liquid additive for waterborne coatings. Like ASCOTRUST® X2, it reacts with metal cations to form stable organic complexes chemically bonded to metal substrates, providing effective chemical passivation. However, ASCOTRUST® X3 is uniquely formulated to offer superior resistance to corrosion in harsh environmental conditions.

- Product Function
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..
- Dosage Information
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 per- formed 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 sys- tems, 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 Information
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 of rust allow to maintain good anticorrosion performances of the coatings, despite the adverse substrate conditions.; It doesn't compromise the coating anticorrosion perfor- mance on non-rusted substrates.; ASCOTRUST-X3 is mainly designed for waterborne pig- mented coatings, and specifically iron oxide containing 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 for- mulation.
