Non-Toxic Fire Retardant Developed

While current flame retardants used on foam products can release toxic substances into the air over time, a natural additive that outperforms conventional substances and is not dangerous to humans has been discovered. The researchers from the University of Texas at Austin found that the water-applied coating, a derivative of the dopamine chemical found in humans and animals, performs around 20% better than existing products in reducing peak heat release rates (a measure of fire intensity).

In addition to its strong tested performance, the polydopamine compound also contains a dihydroxy-ring structure linked with an amine group that can remove free radicals – a crucial step to stopping the spread of fire, as well as produces a protective char coating that cuts off the fire’s access to its fuel source.
