LONDON — Research firm Future Markets Inc. has released a new report, The Global Market for Photocatalytic Coatings. Application of photocatalytic coatings on high-touch surfaces reduces the spread of COVID-19 in essential facilities such as hospitals, public transit, daycares and other public spaces.

Photocatalytic self-cleaning coatings are a significant market for nanoparticulate titanium dioxide (TiO2). Nano-TiO2 surfaces (coated with 10-20nm layer of TiO2) are commercially available and have been used — mainly in the Japanese and European markets — in water and air purification, self-cleaning glass, concrete products and a variety of coatings applications.

These coatings greatly benefit building maintenance, especially for skyscrapers, as they reduce the need for costly surface cleaning. Various types of surfaces with TiO2 can be covered to make them self-cleaning under sunlight as well as room light. Surfaces based on paints, ceramics, glass, and cementitious materials containing active photocatalytic titania nanoparticles have widespread applications to create environmentally clean areas within their proximity. They can also be used to curb the spread of COVID-19 and other viruses. Photocatalytic coating are used in hospitals, acute care facilities, assisted living facilities, senior care facilities, athletic centers, schools, child-care facilities, arenas, airports, and other facilities to reduce the spread of airborne toxins and allergens, such as COVID-19 and MRSA.

Self-cleaning photocatalytic coatings utilizing UV light are currently suitable mainly for exterior use for inorganic surfaces and coatings. Photocatalytic materials operating at the wavelength of visible light are also widely studied. Suitable uses for self-cleaning photocatalytic coatings include:

  • Self-sterilizing, long-lasting clear coatings that kill viruses and bacteria;
  • Self-cleaning architectural glass;
  • Self-cleaning automotive glass;
  • Roof coatings to reduce pollution through the degradation of sulfur and nitrogen oxides;
  • Road and tunnel coatings;
  • Medical — self-disinfecting coatings;
  • Self-cleaning exterior paints;
  • Coatings for the elimination of VOCs and odors in public spaces;
  • Water purification;
  • Indoor air purification; and
  • Self-cleaning solar cell coatings.

In indoor environments, most surfaces, such as ceramic tiles, windows glass or paper, are gradually covered with organic matter such as oils, dirt, and smoke residue and become fouled. Use of photocatalytic coatings that are activated under visible light irradiation can address these issues.

The report will answer the following questions:

  • How large is the current market for Photocatalytic coatings?
  • What is the status of the technology?
  • What is driving deployment of these coatings?
  • What are the potential market opportunities?
  • How can the technology be deployed for anti-viral and anti-microbial surfaces?
  • Who is developing photocatalytic coatings and in what market?

The report also includes 65 company profiles, including products and target markets. Companies profiled include Advanced Materials-JTJ S.R.O., Airlite, EnvisionSQ, Freshlight Solutions, Pureti, MVX Protex, Green Earth Nano Science (GENS), Nanotech Surface Company, FN Nano, Toto and more.
