Simply the best - ALBERDINGK® AC 2403 for metal treatment and multiple applications far beyond!

Salt spray resistance of more than 1500 hours: ALBERDINGK® AC 2403

An Ecolabel capable acrylate dispersion with a maximum adhesion for universal corrosion protection applications.

ALBERDINGK BOLEY GmbH introduces ALBERDINGK® AC 2403, the first commercially available acrylic emulsion that was specifically developed for aqueous corrosion protection applications. Adhesion promoters added during the polymerization phase provides ALBERDINGK AC® 2403 with superior adhesion to all metal substrates, including critical galvanized surfaces. The outstanding corrosion protection properties of this product are made possible by a highly hydrophobic, steam impervious film. Thanks to the extremely low water absorption, the corrosion tendency of the coating is significantly reduced and condensation resistance greatly improved. The innovative production process makes possible a low MFFT, which leads to an extremely low VOC content. A further advantage is the option of formulating the dispersion without the addition of active fillers. Thus by using ALBERDINGK® AC 2403 it is possible to produce a "European Ecolabel" corrosion protection coating.  Furthermore, ALBERDINGK® AC 2403 allows you to produce a non blocking, absolutely tack-free film with a glossy appearance. A very good UV resistance is also achieved, which is an additional benefit to the formulator.  The range of applications for this universal core-shell dispersion includes all corrosion protection applications on metal substrates (Direct-to-Metal). This can be in the area of DIY corrosion protection as well as in the field of classical industrial coating applications. 

UPDATE: Excellent result in NSST

ALBERDINGK BOLEY constantly works on improving its products and starting point formulations - therefore, we are proud to announce that our product documentation on one of our latest products, ALBERDINGK® AC 2403 recently has been updated in order to provide a comprehensive database for various applications already served by this water based dispersion. We have been working very closely with ASCOTEC®, a french producer of anti-corrosion additives, to further boost the salt spray resistance of ALBERDINGK® AC 2403. Because of its unique super-hydrophobic polymer design, ALBERDINGK® AC 2403 already offered > 700 hours of NSST resistance in paint films of only 50-70µm DFT. Thanks to the synergistic effect of ASCONIUM® liquid corrosion inhibitors and ALBERDINGK® AC 2403, we have been able to boost the NSST to > 1500 hours on cold rolled steel at 60-70 µm DFT. Our team of technical experts was able to reach similar performance of more than 1500 h NSST for further formulations which can be used on difficult substrates such as sandblasted steel. These new formulations make ALBERDINGK® AC 2403 an ideal candidate for YOUR next generation of water based 1K maintenance coating systems with very low VOC.
 Besides its use in metal coatings, ALBERDINGK® AC 2403 can be used in a variety of other applications such as:

  • Stain locking primer
  • Concrete coatings
  • Self priming paints
  • MDF Primers
  • Intermediate coats in exterior joinery
  • Stain resistant coatings / enamels
  • “stick to everything” paints
  • Oven-stoving metal coatings
