Product Application

The ASCONIUM® 500 can be added to any type of liquid metal coating for industrial, professional or do-it-yourself use, primers or direct-to-metal systems. It has been specifically designed for water-based formulations based on acrylic, alkyd, epoxy and PU binders, both pigmented and clear-coatings. It is suitable for ferrous and non-ferrous substrates.
The ASCONIUM®-500 is easy to incorporate into the paint formulation, without any pre-dilution into a solvent or pre-neutralization with an amine.
It can be indifferently added to the mill-base or the let-down stage. A post-addition is also possible. In 2K Epoxy coatings, the additive should be added to the hardener part.
Indicative use dosages (% of total coating weight) :

  • 0.8 to 1.5% into 1K formulations.
  • 0.5 to 1.0% into 2K epoxy coatings.
  • 1.0 to 2.0% into 2K Acrylic/PU coatings
