titanium dioxide coating in architectural structures

Titanium dioxide coating: the wonder ingredient

A paint or coating is essentially the combination of two elements: a binder (or resin) and a pigment. Titanium dioxide accounts for 70% of the total production volume of pigments worldwide – it is also known as “titanium white”, the pigment responsible for the white colouring in paint, toothpaste, sunscreen, and more. Titanium dioxide coating uses that same ingredient for many more uses.

Beyond its white colouring, titanium dioxide (TiO2) is used in coatings as a nano particle to provide self-cleaning, antimicrobial, and even smog-eating properties. Imagine the ease of having a coating that keeps itself clean, and even cleans the air.

How titanium dioxide coating on glass makes it self-cleaning

Titanium dioxide has antimicrobial effects, preventing growth on its surface.

Titanium dioxide has antimicrobial effects, preventing growth on its surface.

Most Singaporeans live in apartments. The external glass of the many high-rise buildings quickly becomes grimy from environmental factors and pollution, and then they are dangerous and difficult to clean. Self-cleaning glass takes away these problems. But how does it work?

TiO2 comes in different forms. One (called “anatase”) can be used to make a substrate extremely hydrophilic. A hydrophilic coating “loves water”, attracting droplets to its surface and flattening them out, essentially coating itself in liquid. When it rains this effect causes water to run down the surface like a sheet, taking dirt and grime with it. The TiO2 becomes activated in sunlight, which causes it to interact with dirt and break it down, making it even easier to wash away.

The self-cleaning and hydrophilic properties of titanium dioxide are also used in the medical coatings market, to enhance the lubricity of medical devices. Titanium dioxide coating on metal provides the same properties as with glass.

Fight microbes, pollution and odours with titanium dioxide

One of the benefits of TiO2 is that it breaks down organic matter. This not only works for windows, but also means it works to combat microbial and fungal growth. TiO2 can be added to the surface of cements, tiles, and paints to make them sterilising, antifouling, and even deodorising.

The coating breaks down smells like it breaks down dirt, leaving your substrate protected and your space cleaner and more pleasant. This air-cleaning effect is also why titanium dioxide is being used as a “smog-eating” coating in cities where the pollution levels are at alarmingly high rates. The coating has been shown to absorb oxides of nitrogen (some of the key components of smog) and then they wash straight off the surface with the rest of the dirt.
