Anti-Fouling, Easy-to-Clean and Self-Cleaning Nanocoatings

Anti-fouling, easy-to-clean and self-cleaning nanocoatings have gained market traction, especially in the building materials (anti-graffiti), marine and household (mainly bathroom) sectors. Applications are on surfaces for which contaminants harm the aesthetic, hygienic or technical operation. The goal is both a better level of cleanliness as well as a reduction of cleaning costs.

Anti-fouling, easy-to-clean and self-cleaning nanocoatings have been developed for application in consumer electronics (smartphone waterproof coatings). As well as providing a direct barrier to moisture, hydrophobic coatings are also used for anti-icing, anti-corrosion, anti-fouling, and anti-microbial surfaces.

Future growth will be driven by applications in waterproof electronics and self-cleaning textiles and apparel and household interiors and sanitation, especially in the Asia-Pacific market where there is already strong demand.
