When exposed to heat, the coating will intumesce--foam up to some 200 times its original thickness to make a continuous insulating foam composed of tiny closed cells. According to the manufacturer, this highly expanded cellular foam delays the lateral spread of fire and helps protect the bulkhead, deck or other surfaces beneath. Most important, this delay provides escape time for those aboard and time to reach fire extinguishers and other firefighting equipment. Intumescence takes place right at the start of a fire, when the temperature reaches 300 deg F. This is the critical time in a fire--the point when a fire can still be contained, controlled and extinguished. The thick, tightly adhered foam insulates the subsurfaces from excessive heat, postponing ignition. With a protection span of up to an hour, ignition is delayed long enough for the cause of the heat to be attacked with fire fighting equipment.
