A new Japanese nano technology comes to India that can replace those tinted car window films that were banned by the Supreme Court in April 2012.

This comes in the form of a colourless spray paint that keeps the skin damaging ultra violet and infrared rays from the sun out of the car, yet keeping the car windows transparent as per the Supreme Court regulations.

Fumin Global, the company which owns the global patent for this technology, on Tuesday launched the product under the brand name Stay-Kool in Hyderabad, which will be followed with a national launch at the Delhi Auto Expo.

“This technology not only costs less than half that of the solar control films earlier being used, but also reduces AC energy consumption by 20-30 per cent. It can also be used for buildings, which we will target later,” Ashok Roy, Managing Director, told media persons.

The company has already launched the product in Japan, Singapore, Thailand and Malayasia, which will be followed by Brazil shortly.

When sprayed on the car window glass from inside, the nano-particles in the Stay-Kool liquid form a clear and transparent two-micron thick coating that keeps much of the harmful effects of the sun out.

Arjun Valluri, co-founder of the company, said the cost of spray at the retail level would be Rs 8,000 per sq mt. “This means, for spraying all the four windows of a Swift would cost about Rs 8,000. One coating will last for ten years,” he said.

The company is tying up with Mahindra First Choice initially to reach car owners, who can get their car windows sprayed with the product at an authorised service centre.
