Flame Control No. 173 Aircraft is a highly flexible, intumescent type, fire resistant coating. When attacked by fire and/or high heat, the coating puffs up (intumesces) and forms a thick, dense fire barrier, thus affording maximum burn through (fire) protection. This foam layer retards the penetration of heat to the substrate, thus insulating the surface.
Aluminum panels 0.050 inches thick, coated with No. 173 to a dry film thickness of 0.033 inches, have successfully passed the standard FAA 2000°F fire test, while being subjected to simulated engine take-off and operating conditions. The coated panels completed the FAA 15 minute requirements, with approximately a 50% time safety margin (in excess of 22 minutes before failure).
Flame Control No. 173 possesses outstanding properties in the following categories. Fire resistant (thermal insulating and burn through protection), adhesion to primed and bare aluminum, metal, and alloy substrates, flexibility, and crack resistance under continuous vibrating conditions.
