Flame Control No. 173 Fiberless is a highly flexible intumescent type, fire resistant coating. It was developed primarily for the aircraft industry as an economical means of affording maximum fire protection to lightweight metals, such as aluminum, magnesium, etc.. 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.
Flame Control No. 173 Fiberless 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.
