It’s possible you’ve heard of what many consider to be “the next big thing” in the coatings industry: smart coatings. Smart coatings are making quite a splash in the industry, with a compounded annual growth rate of nearly 50 percent and broad applications across automotive, marine, aerospace, military, construction, textiles, and electronics. So what makes a coating “smart”, exactly? Smart coatings are finishing materials that respond intelligently and adapt to various mechanical, electrical, thermal, and optical stimuli. These responses fit into a number of categories: self-healing, self-cleaning, corrosion sensing, antifouling, antimicrobial, thermochromic, electrochromic, photochromic, and self-dimming. We’ll look more closely at a few of these categories here.


Self-Healing

When the coating is physically damaged, the self-healing intermediate layer physically repairs the damage autonomously, closing and sealing the gap and providing an active physical barrier. The adhesion between the primer and topcoat are preserved.


Self-Cleaning

The super-hydrophobic coating creates a protective layer of air between a surface and the environment preventing water, dirt, and oil from adhering to the treated surface. These coatings are a real on-market product, but so far are mostly low-performance and not very long lasting.


Antimicrobial

Antimicrobial materials were first introduced about 10 years ago and have gained wide use as a finish capable of protecting an object from degradation due to bacteria, viruses, and mold. A handful of powder coating manufacturers offer this technology to a broad array of manufacturers, including hospital equipment, public transit, food handling, medical equipment, and playground structures.


Smart Protective Coatings

Anti-icing, anticorrosion, and anti-fouling fall under the category of “smart protective coatings”, since they each share a common purpose and functionality. For example, smart anti-icing coatings can reduce the amount of antifreeze used and therefore lower the amount of corrosion that traditional anti-icing treatments cause.


There are more examples of smart coatings, but not every smart coating is a winner - yet. In some cases, this is just because the technology is so far from being commercialized that it might take a decade to generate any revenues at all. Still, the above-mentioned classifications of smart coatings are already out there, some only in niche markets, but we can expect to see them grow exponentially.
