The addition of micro- or nanocapsules, loaded with corrosion inhibitors, into coatings is another approach to achieving a protective coating with self-healing attributes. Capsules are typically constructed from polymers, inorganic materials like silica and titania and calcium carbonate [ 34 41]. However, due to the toxicity of hexavalent chromium, environmental and human health concerns have restrained their use and alternatives are being studied all over the world. Our goal is to engage customers as partners in developing new corrosion-resistant coating products.. The coatings have tailored functionalities such as anti-corrosion, self-healing, scratch resistance, anti-ice, and easy-to-clean. NEI has developed a line of self-healing top coats, where a physical self-healing phenomenon leads to gap closing and crack sealing.
