TO 1-1-700 MIL-PRF-81733, SEALING AND COATING COMPOUND, CORROSION INHIBITIVE 48 c. Faying surfaces that are to be adhesive bonded shall be treated and processed as specified by the approved bonding procedure in the applicable system specific maintenance manual. SAE AMS-S-8802, SEALING COMPOUND (POLYSULFIDE) 62 SAE AMS-3276 (MIL-S-83430), SEALING COMPOUND, INTEGRAL FUEL TANK 59 SAE AMS-3276 (MIL-S-83430), SEALING COMPOUND, INTEGRAL FUEL TANK 59 a. For permanent structure, all faying surfaces, seams, and lap joints outside of fuel wet and high temperature areas shall be protected with MIL-PRF-81733, Type II or IV, Class 1 or 2, Grade A sealant. Apply the sealing compound to one or both surfaces and squeeze the part together to ensure the complete coating of the entire mating or faying surface. Excess material squeezed out shall be removed so that the fillet remains at the joint edges. The fillet width shall not be less that 1/4 inch. For seams, the sealant shall fill the seam entirely up to flush with the surface. Joint, joggle, or cavity areas which could hold water shall be filled with MIL-PRF- 81733, Type II, Class 1 or 2, Grade A, SAE AMS-S- 8802, Class B, or SAE AMS-3276, Class B sealant. PR-1773, SEALING COMPOUND, LOW ADHESION, NON-CHROMATE CORROSION INHIBITORS 57 d. On faying surfaces, seams, or joints which require disassembly for maintenance, either SAE AMS 3267 (MIL- S-8784) or part No. PR-1773 low adhesion sealant shall be used (part No. PR-1773 sealant contains non-chromate corrosion inhibitors). NOTE SAE AMS 3255 (Skyflex®) sealing tapes or Av- DEC® HT3935-7 and HT3000 sealing tapes may be used in lieu of the low adhesion curing type sealants in many removable joint areas requiring periodic disassembly for maintenance when approved by the equipment SPM. MIL-PRF-23377, TYPE I & II, PRIMER, EPOXY CHEMI- CAL AND SOLVENT RESISTANT 38 MIL-PRF-81733, SEALING AND COATING COMPOUND, CORROSION INHIBITIVE 48 TT-P-2760, PRIMER, POLYURETHANE, ELASTOMERIC, HIGH SOLIDS 67 b. If sealing is impossible because of mechanical or other factors, prime both surfaces with two coats of MIL- PRF-23377, Type I, Class C Epoxy Primer, or TT-P- 2760, Type I, Class C Polyurethane Primer, per instructions in TO 1-1-8. SAE AMS-S-8802, SEALING COMPOUND (POLYSULFIDE) 62 SAE AMS-3276 (MIL-S-83430), SEALING COMPOUND, INTEGRAL FUEL TANK 59 12-30
TO 1-1-700 e. On plastic components, the joints shall be suitably sealed and faired into the adjacent surfaces with MIL- PRF-81733, Type II or IV, Class 1 or 2, Grade A, SAE AMS-S-8802, Class B, or SAE AMS-3276 sealant, unless otherwise specified in the applicable system specific maintenance manuals, to stop the formation of pockets which will entrap moisture, dirt, etc. NOTE MIL-PRF-81733, Type II or IV, Class 1 or 2, Grade A sealant shall be used for rivets that require wet installation on plastic components. 12.7.2 Fillet Sealing. The fillet, or seam, as shown in Figure 12-10, is the most common type of seal. Fillet seals are used to cover structural joints or seams along stiffeners, skin butts, walls, and to seal around fittings and fasteners. This type of sealing is the most easily repaired. It should be used in conjunction with faying surface sealing and in place of it if the assembly sequence restricts the use of faying surface sealing. 12.7.3 Injection Sealing. This type of seal, as shown in Figure 12-11, is used primarily to fill voids created by structural joggles, gaps, and openings. USE ONLY THOSE SEAL- ANTS RECOMMENDED BY THE EQUIPMENT MANUFACTURER. Force sealant into the areas using a sealant gun. This method is a means of producing a continuous seal where it becomes impossible to lay down a continuous bead of sealant while fillet sealing. Clean the voids of all dirt, chips, burrs, grease, and oil before injection sealing. 12.7.4 Fastener Sealing. Figure 12-12 illustrates techniques used to seal different types of fasteners. Fasteners are sealed either during assembly or after assembly. Install them wet with sealant in accordance with requirements in the applicable system specific maintenance manual for fasteners in permanent structures. To seal during assembly, apply the sealant to the hole or dip the fastener into sealant, and install fastener while sealant is wet. For removable parts, coat the lower side of the fastener head only. Do not coat the hole or the fastener shank or threads, as this makes future removal almost impossible without damage to the part. To seal after assembly, cover the pressure side of the fastener with sealant after installation. Corrosion damaged areas in the countersinks around removable and fixed fasteners may be filled with the fastener in place. Cadmium coated fasteners that have been blasted or abraded during corrosion removal shall be primed in accordance with the applicable system specific maintenance manual and TO 1-1-8 and then coated with MIL-PRF-81733, Type I, Class 1 or 2, Grade A sealant. 12.7.5 Form-In-Place (FIP) Gasket Sealant Repair. After removal of all loose sealant material, thoroughly clean the area to be resealed per paragraph 12.6.1. Areas of the old seal to which new sealant will be added must be cleaned and abraded using an abrasive mat or abrasive cloth (see Appendix A in TO 1-1-691) to expose a clean, fresh surface.
