Effective Strategies to Combat Corrosion with Advanced Coatings

Mitigating Corrosion with Advanced Coatings

Corrosion is a persistent challenge across various industries, compromising the integrity of structures and materials. An effective strategy to mitigate this issue involves the application of advanced coatings, which provide robust protection against different corrosive mechanisms.

Barrier Protection

Barrier protection is one of the primary methods to decelerate corrosion. This technique leverages the impermeability of the paint film, ensuring a physical barrier that prevents moisture and contaminants from reaching the substrate. Key factors contributing to effective barrier protection include:

• Film Thickness: A thicker paint film offers increased resistance to permeation.
• Micaceous Iron Oxides (MIOX^®): These lamellar structures enhance the film's impermeability, providing superior barrier protection.
• Graphene: Known for its exceptional properties, graphene offers a novel approach to enhance the protective capabilities of coatings.

The structure of lamellar micaceous iron oxides significantly contributes to the coating's impermeability.

Sacrificial Protection

Sacrificial protection is another key strategy, involving the addition of a more reactive metal that will corrode instead of the base metal. A prime example of this approach is the application of Zinc Rich Coatings, which contain zinc dust. Here, zinc acts as the sacrificial anode, surrendering to corrosion to protect the underlying steel.

Inhibitive Protection

Inhibitive protection aims to slow down the oxidation-reduction reactions that lead to corrosion. This method often uses pigments such as zinc-based or zinc-free varieties, including:

• NUBIROX^®: A zinc-based pigment that offers excellent inhibitive properties.
• SHIELDEX^®: A zinc-free option tailored for specific environmental conditions.

Inhibitive pigments like NUBIROX^® and SHIELDEX^® enhance coating performance in various conditions.
