    • 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.


    APPLICATION
    ASCOTRUST-X4 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-X4 is designed for any kind of waterborne
    coatings, pigmented or not, based on various binder
    technologies : acrylic, alkyd, epoxy, PU...
    It is recommended to use an organic-type anticorrosion
    agent when ASCOTRUST-X4 is added to a metal paint
    formulation.


    FEATURES
    • Ready-to-use and easy to incorporate liquid
    • VOC-free
    • Compatible with most waterbased binders
    • Eco-friendly* additive
    • Synergic action with antiflash-rust additives
    • Doesn’t change color of coatings


    INCORPORATION / DOSAGE
    ASCOTRUST-X4 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: ASCOTRUST-X4 should be added to
    the hardener (amine part).
    Indicative use dosages (% of total coating weight) :
    • 0,5 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.
