Fire Seal is a water based intumescent fire retardant latex coating for interior and exterior (top-coating required) applications. When subjected to fire, it swells 60 to 100 times than that of its original thickness forming a stable and inert carboneous char which forms a physical barrier between the flame and the substrate. This char thermally insulates the substrate from heat and stops the availability of oxygen required for fire initiation. It provides effective heat shield and insulation to the substrates. It provides fire protection to most metallic and non-metallic substrates.
