Researchers from the IDONIAL Foundation have developed an innovative approach to enhance corrosion protection for galvanized steel using self-healing coatings with microencapsulated active substances. Corrosion remains a significant challenge in industries, as even minor coating defects can lead to metal degradation. Traditional coatings, while cost-effective and easy to apply, are prone to cracking and require frequent repairs or replacements.

This study focuses on the microencapsulation of self-repairing agents, protecting their integrity and functionality until activated by damage to the coating. By isolating these agents in microcapsules, problems such as leaching or premature reactions, which are common when directly adding additives to the coating matrix, are prevented. This technology, integrated into a sol-gel coating specifically designed for galvanized steel, offers enhanced corrosion resistance and the ability to self-repair, extending the lifespan of coated materials in industrial environments.

This work will be presented at the SMS Smart Materials and Surfaces 2024 Conference.
