GeoCoat is a synergy between earth friendly waste material and great fire retardant requirements for a novel fire retardant coating material particularly on metal substrate. The main component used is rice husk which is a waste source, and the novel formulation of GeoCoat is optimized using statistical analysis tool. Currently, existing fire retardant use many additional agents including foaming, blowing and charring. With the latest novel optimized formulation, GeoCoat is able to protect the substrate by delaying the time taken. The coating also did not release any smoke and will never ignite when get in touch with fire.
