Form This specification covers fuel-resistant@ two-component polysulfide synthetic rubber compounds which cure at room temperature. Application This sealing compound has been used typically for sealing and repairing integral fuel tanks@ cabin pressure sealing@ and aerodynamic smoothing@ but usage is not limited to such applications. It may be used for faying surface sealing@ for wetinstallation of fasteners@ for overcoating fasteners@ and for sealing joints and seams. The sealing compound can be used in fuel areas as well as in non-fuel areas. It may@ in some cases@ be used as a non-structural adhesive. The sealant is capable of continuous service use from -65 to +250 ??(-54 to 121 ??. AMS3100 adhesion promoter may be applied prior to application of the sealant. Classification Types Sealing compounds covered by this specification are classified as follows: Type 1 - Dichromate Cured Sealant. Material with a dichromate curing agent. Type 2 - Manganese Dioxide Cured Sealant. Material with a manganese dioxide curing agent. Classes The following classes apply to both Type 1 and Type 2 sealing compounds: Class A - Suitable for application by brush. Available in the following application times in hours: A-1/2 A-1 A-2 Class B - Suitable for application by extrusion gun or spatula. Available in the following application times in hours: B-1/2 B-1 B-2 B-4 Class C - Suitable for extrusion gun@ spatula@ brush@ or roller. Available in the following application times in hours: Notation: ( ) Assembly time in hours: C-8(20) C-8(48) C-24(80) Safety - Hazardous Materials Shall be in accordance with AS5502 (1.1).
