A research chemist has developed paints made from rice husks able to resist bullets, fire, bacteria or rust.
The paints were introduced by Nguyen Thi Hoe, chairman of Kova Paint Corporation, who says the main material used to make all four paints was the nano silica found in the rice husk. According to Hoe, the bulletproof paint vest requires less layers than conventional vests, so is lighter to wear, and was able to stop a bullet shot from 2 meters away. She also claims the flame-resistant paint can protect a surface for 2 to 6 hours, the anti-bacteria paint can kill up to 99 percent of bacteria, and the rustproof paint can keep an object under the sea rust-free for up to 10 years
