Commercial production for a self-cleaning coating

By Gerald Ondrey |

Last month, PJI Contract Pte Ltd. (Singapore; www.pjicon.com.sg) opened a production facility for the manufacture of titanium dioxide solution — a self-cleaning, nanocoating material developed at Singapore Institute of Manufacturing Technology (SIMTech; www.simtech.a-star.edu.sg), a research institute of the Agency for Science, Technology and Research (A*Star; Singapore; www.a-star.edu.sg). PJI Contract has licensed the patented TiO2 manufacturing process from A*Star, and has already applied the self-cleaning coating on the facades of several commercial buildings. The self-cleaning properties of the TiO2coating technology are derived from the oxidative and hydrophilic nature of the coating. When exposed to sunlight, TiO2 catalyzes the oxidation of organic compounds and microbes. Water is repelled by the hydrophilic coating, and thus washes away dust and dirt. The coating has been recognized by Singapore’s Building and Construction Authority’s Green Mark Scheme. In addition to using the technology for self-cleaning coatings for buildings, PJI Contract plans to make the coating available in a spray can for the consumer market. The company anticipates the TiO2 coating will become one of its top-ten revenue generators.   Click…
