Scientists from Nanyang Technological University (NTU), Singapore, and national industrial developer JTC have unveiled what they are calling a 3-in-1 coating for better fire and corrosion protection.

‘In a fire, our coating forms a compact charred layer that acts as a protective barrier against the heat,’ explained Aravind Dasari, a Principal Investigator at the NTU–JTC Industrial Infrastructure Innovation Centre.

Called FiroShield, the coating functions like regular paint and is easy to apply, according to the research team. It can be applied on bare steel without the need for sand blasting, and provides protection against fire for two hours. 

Dasari explained, ‘While typical fire coatings will also form a charred layer, those are thick and foam-like, which can fall off easily and leave the steel exposed to the fire. What we aimed at was an innovative coat that works differently from conventional intumescent coatings and can stick to the steel surface for as long as possible under high temperatures, and yet has durability and weather resistance under normal conditions without a need for a top coat of paint.’
