How to slow down corrosion with coatings?
Barrier protection; Impermeability of the paint film, film thickness, lamellar micaceous iron oxides (MIOX®) or GRAPHENE.
Sacrificial protection: Addition of a more sensitive metal to corrosion.
Example: Zinc Rich Coatings (Zinc Dust). Zinc works as sacrificial anode and it is corroded instead of the steel.
Inhibitive protection: Slowdown oxydo-reduction reactions, Zinc based or free zinc pigments (NUBIROX®, SHIELDEX®)
