COMBUSTIBLE DELAY BARRIERS

摘要

A combustible coating for providing a delay barrier to intrusion into an object. The coating contains a source of fuel as a metal and/or a polymer and a source of oxygen such as an oxidizer. The coating is ignitable at a temperature in excess of about 300 DEG C., during combustion is resistant to the effects of common fire extinguishing materials, and is capable of sustaining combustion for at least five minutes with a burn rate of no more than about six inches per minute.
