Invisible coating that makes wood “fireproof”
SINGAPORE -- Researchers at Nanyang Technological University has developed a coating that they say makes wood “fireproof’ while allowing the woodgrain to show through. The coating, about 75 microns thick, creates a flame barrier when activated by fire.
When heated by flame, a series of chemical reactions happen, causing the coating to become a char that expands to more than 30 times its original thickness. This char prevents the fire from combusting the wood underneath, as shown in an accredited lab test.
