This specification covers three types and three classes of fuel-resistant polysulfide sealing compound with low specific gravity, supplied as a two-component system which cures at room temperature. Changed adhesion promoter substrate requirements. Added a “no immersion” peel strength test. Increased maximum base viscosity requirement to 18000 poise (1800 Pa•s) to coincide with AMS3277. Removed Viscosity of Curing Agent requirement. Removed minimum swell requirement. Removed minimum flow requirement for Class B materials. Removed -80 °F storage life requirement for pre-mixed and frozen sealing compound to coincide with other polysulfide sealing compound requirements. Removed Chalking as a Initial Acceptance Test. Additional clarification to current requirements and editorial corrections were specified.
