Epoxy zinc rich primer coating belongs to zinc coatings which are applied to protect ferrous surfaces from corrosion. So the zinc based primer coating provides cathodic protection for the steel surfaces. Because zinc is anode to steel, these particles corrode first, thus protecting the ferrous substrate beneath the primer from corrosion. Being a trustworthy enterprise, Protexion presents a comprehensive assortment of epoxy zinc rich primer coating. Our offered product is highly demanded for the purposes of coating oil tankers.
Zinc rich primer coatings are designed for application on blast cleaned steel. This Epoxy Zinc Rich Primer coating is compatible with every type of coating and is most commonly used as a prefabrication primer. It can be used even without overcoating to protect the inside of cargo tanks in oil – tankers and ships.
What is Epoxy Zinc Rich Primer?
Epoxy Zinc Rich Primer is a two-pack process enriched with metallic zinc to provide superb efficiency in a highly corrosive environment. Metallic zinc provides cathodic protection for base metal groups and Epoxide reacts with polyamide / amine adduct hardener to form hard, non-convertible film at ambient temperatures. It resists photo degradation by UV light as it contains UV absorber.
The zinc particles are more active than steel and act as anodes in the coating that corrode sacrificially instead of the steel when they are exposed to water, oxygen, and/or chlorides. Epoxy Zinc rich primer coatings are primarily used to protect steel structures from corrosion; and organic zinc-rich primers are often preferred over inorganic zinc-rich primers because they are less sensitive to surface preparation, over application, and humidity, making it easier to apply.
Safety Precautions to Take When Applying Epoxy Zinc Rich Coating:
Do not inhale solvent vapour or paint mist with a face mask. Use goggles and gloves to protect against direct skin and eye contact with paint.
Clean with fresh running water in case of pollution and seek urgent medical assistance.
Keep the material away from fire, lightning and direct flames
Provide sufficient ventilation while working with solvent based paints in confined spaces and stagnant air.
Protection Mechanism of Epoxy Zinc Rich Primer Coating
Initially, once the epoxy zinc rich primer coating and the top coating are applied on the substrate as a continuous layer, the coating system acts as a barrier to corrosive environments. The coating fully isolates the substrate from the environment.
Only after a defect is formed in the coating, thus partially exposing the substrate to the corrosive environment, does the zinc rich primer layer play its part in providing sacrificial corrosion protection to delay the onset of the electrochemical reaction (corrosion) of the substrate.
The amount of sacrificial protection provided depends upon variables such as the purity of the zinc dust used, the presence of moisture, and the electrical conductivity between the substrate and interconnected zinc particles. Thus, the zinc used in the primer is anodic to the ferrous substrate that acts as a cathode. Once the zinc particles are converted into zinc oxide, the sacrificial protection will end.
