3M India’s R&D team has developed a first-of-its kind solution named 3M Scotchkote Polytech Exp RG700. This is a solar reflective coating which, as the company informed, reduces heat inside any enclosure and can be applied on various metallic and non-metallic substrates.

“This innovation is a significant milestone in 3M India’s R&D effort. We are greatly satisfied with the impact this solution has had on the Indian rail coaches’ heat reduction so far. Our teams are now scaling up the production as this solution finds prevalent application in the HVAC industry. We are also exploring application of this solution across other countries such as Singapore, Germany and China,” said Dr Mukesh Madhup, manager technical, Product Development, Electrical Markets Division 3M India.

diverse application across enclosures that have electronic components

The solution, as 3M informed, finds diverse application across portable cabins, automotive-vehicle exterior, two-wheeler covers, buses, metros, telecommunication, refrigeration, cooling, chemical plants, industrial shed roofing, pavements, Liquified Petroleum Gases (LPG) storage tanks, pipelines and outdoor enclosures that have electronic components.

“To meet these parameters, the reflective coating product was developed after 2.5 years of extensive research led by 3M India R&D and supported by manufacturing and product stewardship leaders. There are several factors that led to this innovation, such as the growing threat of global warming, urban heat island formation, growing regulation to conserve energy and HVAC industry’s quest for surface temperature reduction. This solution has led to the overall improvement in AC’s efficiency, protecting enclosures and surfaces from the heating due to solar infra-red radiation,” read 3M’s official statement.

3M’s Skotchkote Poly-Tech RG700 has so far been applied in over 100 rail coaches. It is believed to have contributed to Indian Railways vision of sustainable procurement, passenger comfort and energy conservation by over 20 per cent. Additionally, it has significantly contributed to passenger comfort. It is estimated that if applied over 15,000 rail coaches in India’s large rail network, this solution can save up to 162 thousand megawatts of electricity which converts to reduction in the amount of CO2 released by almost 132 thousand tonnes per year. This could potentially save approximately $15 million per year in energy costs or reduce it by 17 per cent.

“The product was recognised with an honorable mention for ‘World Changing Idea’ by Fast Company in the ‘Energy Category’ as part of their listing for the year 2020. They called out 3M Skotchkote’s impact on Indian rail coaches in reducing the temperature inside the coach by 15 per cent. This has led to significant improvement in passenger comfort in non-AC coaches. This coating was also applied on the roof of air-conditioned coaches to enhance energy efficiency of the air-conditioners, thereby reducing its HVAC cost by 20 per cent,” read 3M’s official statement.
