HA NOI (VNS) — The first-ever fire-resistant paint produced from rice husks by a Vietnamese company was introduced to the public recently, the Voice of Viet Nam (VOV) reported.

The paint, produced by the Kova paint group using nanotechnology, can resist flames with temperatures of 800 to 1200 degrees Celsius and does not release toxic gas, its inventor and Associate Professor Nguyen Thi Hoe, who has received Russia's Kovalevskaya award for her contributions to science, said.

Other kinds of similar paints in the market can resist fires of only 500 to 600 degrees Celsius.

Hoe said tests had shown that her paint's quality was better than those of similar products from Singapore or Germany.

She said 12 tonnes of rice husks were burned to produce one tonne of ash, which was then used to create paint that was fire-resistant for 360 minutes, exceeding the highest standard stipulated by Vietnamese technical regulations.

Nguyen Khoi, technical director of the Kova paint group, said the paint cost only one-third the price of exported fire-proof paints that cost US$50-$100 per square metre. However, the price of the Vietnamese paint is still high, partly because of the cost of transporting rice husks to factories.

Tran Trung Thanh, deputy head of the department of fire prevention and control, rescue and salvage under the public security ministry, said the paint was made of rice husk, which is agricultural waste, providing income to farmers.

Nguyen Thi Hoe has also invented bulletproof paint, self-cleaning paint and antibacterial paint.

A series of fires and explosions have recently occurred across the country, especially in production bases and industrial parks, causing huge losses to human life and property.

According to the department of fire prevention and control, rescue and salvage, nearly 2,800 fires killed 62 people last year, and destroyed property worth about VND1.5 trillion (US$669.4 million) and more than 1,600ha of forests. — VNS
