Lockheed Martin MA2RK Trowelable Coating Kit, 1 qt, Solid, Reddish Brown, 30 +/-3 lb/cu-ft, 183 Days

MA-25S® is a medium-density, room temperature curing, ablator/insulator, which has been used extensively for thermal protection on aircraft and space launch vehicles. On the space shuttle, short duration exposure to temperatures exceeding 1200 deg F may be encountered. The sprayable material (Type I) can be applied using standard spray equipment for large area primary applications. The trowelable/moldable material (Type II) can be used for small area applications or as a repair material for damage to the sprayable insulation.
