This specification covers a polysulfide (T) rubber sealing compound with nonchromated corrosion inhibitors supplied as a two-component system which cures at room temperature. The compound has been used typically for faying surface sealing and for wet-installation of fasteners in aircraft structural joints, but usage is not limited to such applications. It can be used in non-fuel areas for fillet sealing and overcoating fasteners, for sealing joints and seams, cabin pressure sealing, and aerodynamic smoothing. AMS 3100 adhesion promoter can be applied prior to application of the sealant. This material is usable for continuous service from -65 to 248 degrees F (-55 to 120 degrees C), with short-term exposure (approximately 6 hours to 360 degrees F (182 degrees C).
