Solar heat-reflective coatings for energy savings

Solar heat-reflective coatings for buildings and other infrastructure can save energy and reduce the carbon footprint, AS Khanna explains the energy- and money-saving coatings and where they can be used.

Today, India is trying to reduce its carbon footprint by producing electricity through alternative energy, especially wind and solar power. However, it is also possible to use a simple paint coating on a rooftop to bring down the structure’s temperature, thereby consuming less power for air-conditioners or coolers.

Initially, the main purpose of paint coatings was aesthetics and corrosion protection for steel and concrete structures. But their scope has widened substantially. Today, the market offers high-performance, functional and eco-friendly coatings. Several kinds of coatings are now function-specific—for acid-resistance, high temperature-resistance, automotive use, concrete and plastics. In addition, many coatings are characterised as ‘smart’ as they do more than just protect the surface. These include hydrophobic, self-cleaning and self-healing, conductive, anti-bacterial and anti-dust coatings.

Recently, a new kind of smart coating that can cool roofs has been developed that saves electricity and reduces the carbon footprint by reflecting about 89 per cent of the infrared (IR) heat absorbed from the sun. In addition to heat reflection, the coating also has an insulation effect. Thus, such a combination can bring down the ambient temperature in a room, say from 45oC to 37oC.
