A flame-retardant finish is a treatment applied to materials, such as fabrics and plastics, to reduce their flammability. This finish helps slow down the spread of fire, giving people more time to escape and reducing the risk of severe damage. It is commonly used in items like upholstery, curtains, and children's clothing. The chemicals used in flame-retardant finishes can vary, but they are designed to either prevent ignition or inhibit the combustion process. Many industries, including construction and textiles, utilize these finishes to enhance safety standards and comply with regulations regarding fire hazards.
