Product Information
On the Space Shuttle, short duration exposure to temperatures exceeding 1200°F may be encountered. In aircraft engine applications, continuous use temperatures range between 300-600°F. The MA-25S material has been FAA certified for fire proof protection of fan thrust reversers per FAR Part 25.1181a and FAA Advisory Circular AC 20-135.
The material is a filled elastomeric silicone which is available in either a sprayable or trowelable form. 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. MA-25S can also be obtained in pre cured sheet form for secondary bonding applications.
