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).
USES:
- Developed primarily for the aircraft
industries as an economical means of
affording maximum fire protection to
lightweight metals, such as aluminum,
magnesium, etc
