Sealing Compound, Integral Fuel Tanks and General Purpose, Intermittent Use to 360°F (182°C)
- Aerospace Material Specification
This specification covers five classes of a fuel-resistant polysulfide (T) sealing compound supplied as a two-component system.
This sealing compound has been used typically for fuel tank sealing, cabin pressure sealing, and aerodynamic smoothing, but usage is not limited to such applications. It can be used for faying surface sealing, for wet-installation of fasteners, for overcoating fasteners, sealing joints and seams, and nonstructural adhesive bonding. This room-temperature curing sealing compound can be used in fuel areas as well as nonfuel areas. Curing of this material can be accelerated at higher temperatures. Prior to applying this fuel tank sealant, the bond surfaces should be treated with AMS 3100 adhesion promoter to enhance sealant adhesion. This materials is usable from -65 to 250 degrees F (-54 to 121 degrees C), with short-term exposure (approximately six hours) to 360 degrees F (182 degrees C).

Scope AMS Committee G9, Aerospace Sealing, shall be primarily concerned with the sealing of aerospace vehicles for fluid containment and environmental protection by the use of sealants which are applied and cured to solid materials or are permanently mastic. This includes the preparation of sealant material specifications, aerospace recommended practices for sealing processes and related activities. Examples of applications are the sealing of integral fuel tanks, fuel cell cavities, crew compartments and passenger areas, access doors, fasteners, avionics compartments, windshields, firewalls, etc. The committee shall also be involved with elastomeric fuel cells. The committee shall address the effort on the environment of cured and uncured sealant materials and their containers and recommend approved practices for their proper disposal. The committee shall also be involved with elastomeric fuel cells. The committee shall participate in discussions on various sealing materials and processes and provide comments and views on relevant research and development efforts.
