Spinoff from a Mooncraft TechnologyAvco Specialty Materials' Chartek III fireproofing provides longterm fire protection for structural steel in high risk industrial applications such as structural conduits, pipes and valves of offshore platforms, and storage tanks used in hydrocarbon processing industry. In the presence of fire, Chartek III fire-proofing provides two kinds of protection. One of them is ablation, technique used on Apollo involving dissipation of heat by burnoff. The other is called intumescence or swelling. Heat causes the Chartek coating to swell to a thickness six times greater than when it was applied forming a protective blanket of char that retards transfer of heat to the steel structure. Mesh reinforcement keeps the char intact and reduces metal fatigue. Chartek provides fire protection for as much as two or three hours depending on the type of fire and the thickness of the coating applied.
