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).
