Refractory phosphate: Analysis of the "safety shield" of building fire protection

Where high-rise buildings stand, fire hazards are everywhere. Refractory phosphates will be converted into an expanded carbon layer when exposed to fire, with a thickness equivalent to a three-centimeter steel plate, isolating oxygen and heat. A building test: The fire resistance time of the board coated with this agent exceeds the national standard by 1.5 times. It is halogen-free and low-toxic, and the smoke concentration is reduced by 70% when burning, which meets the environmental protection needs of modern buildings. Today, it is widely used in office curtain walls, home panels, electronic product shells, etc. Our company has also developed an ultra-thin product with a 0.1 mm coating that can reach the flame retardant V0 level. It is both safe and beautiful.
