Fire retardant coatings for fabrics are essential for enhancing fire safety in various applications, from textiles to industrial materials. These coatings work by inhibiting the ignition and spread of flames, reducing the risk of fire damage and protecting lives. Here's a breakdown of how they work:   How Fire Retardant Coatings Work: Physical Barrier: The coating forms a protective layer on the fabric surface, acting as a physical barrier that slows down heat transfer and oxygen supply to the underlying material. This delay in heat and oxygen reaching the fabric's core can significantly reduce the likelihood of ignition.   Chemical Reaction: Many fire retardant coatings contain chemicals that undergo endothermic reactions when exposed to heat. These reactions absorb heat from the surrounding environment, cooling the fabric and slowing down the combustion process.   Char Formation: Some coatings promote the formation of a char layer on the fabric's surface. This char layer acts as an insulating barrier, further hindering heat transfer and oxygen supply to the underlying material.
