sealant to airframe faying surfaces. Specifically, this effort evaluated a new, more cost-effective, revolutionary approach for providing the corrosion protection and seal-ing characteristics required for faying surfaces. This overall program was established to evaluate and compare the various factors of the existing wet-sealant
polysulfide sealant, MIL-S-81733. The use of sealant on the faying, or mating, surfaces prevents the chan-neling of fuel along the joint to a point remote from an internal leak source. This considerably simplifies any subsequent leak detection procedures. A second and very important function of the faying surface seal is to

Fluid sealing between faying surfaces utilizing a solid sealant. United States Patent 6133371. Abstract: A sealant for forming a fluid seal between the faying surface of two metallic substrates that are compressively and mechanically joined together. The sealant is a liquid in its pre-cured condition and a dry solid in its cured condition.
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.
ing 'Seal Welds,'" by Duane Miller, provides good guidance on the variances required for seal welding. For bolted connections, whether bearing or slip-critical, the elements are individually galvanized and then assembled. The galvanizer will simply ensure that the bolt holes are not blocked with excessive amounts of zinc. The faying ...

PS 892 CM was especially developed for use over a temperature range of - 55°C + 120°C and will resist aircraft fuels (aviation gasoline or jet fuel), oils and ...
Faying-surface sealing was not used on earlier model aircraft due to a belief that applying an elastic sealant in the faying surfaces was structurally unacceptable and would result in excessive flexing of the wing. It has since been proven that faying-surface sealing, properly accom-plished, does not degrade the structure and offers a big
Sealant should not be used for faying surface applications unless it has just been removed from refrigerated storage or freshly mixed. While the use of sealants on aircraft surfaces has greatly increased over the past few years, application methods have been mostly through the use of brushes, dipping, injection guns, and spatulas. ...
The faying-surface seal is not considered to be a primary fuel barrier seal, except in adhesive-bonded systems; the faying surface seal, however, does play an extremely important role as a secondary fuel barrier seal. It limits the length of a leak path and is a permanent, stable, protected, and essentially non-dislodgeable seal that is ...
This condition can be eliminated by sealing the faying surfaces in a manner to exclude moisture. Proper protective coating application with inorganic zinc primers is also effective in reducing faying surface corrosion. Oxygen Concentration Cells. A water solution in contact with the metal surface will normally contain dissolved oxygen.
surface grade material, easily applied by spatula, brush, roller or extrusion gun. They maintain flexibility and bond strength on most metal substrates under extremes of temperature, weathering, and stress. Applications • Sealing faying surfaces of mating parts • Sealing joints from the passage of liquid or air
Faying surfaces are used to fasten or join two or more members to form a strong structure. To prevent corrosion between the two surfaces, primers or sealing agents are used to provide an air- and moisture-tight joint. In the faying surface failure situation, gaps are created due to primer or sealing agent leakage, which allows air or moisture ...
Faying Surface: All sealants were mixed in accordance with manufacturer's instructions and a smooth even coat of sealant (thickness of 0.005 inch) was applied to both sides of the mating panels using an orange stick or glass rod (Figure 4). Five mil bond wires were used to control the thickness and the panels were placed together so the holes ...

Developing a smooth surface is also essential, but in most cases crevices develop on these faying surfaces; most fabricators use sand blasting to provide a clean and even surface. However, sealing or coating attempts are made to minimize and avoid the occurrence of gaps; the environment of the two surfaces also matters a lot when making the joint.

With painted faying surfaces, the slip resistance is determined by the tested performance of the paint system as meeting Class A, B, or some other intermediate slip coefficient and the steel to be painted must be blast-cleaned in all cases. Roughened (see 6.7.4) hot-dip galvanized surfaces also provide a Class A slip coefficient, μ=0.30.

When applying the BMS595 sealant to the electrical faying surface, do you also cover the electrical bond area. My interpetation of Boeing Spec BAC5117-6 2 is that you apply the sealant to the entire faying surface of one part. I'm dealing with an aluminum assy and there is a bracket to be installed with a small "bare" area on the bracket ...
improving drainage and sealing of edges or keeping crevices as open as possible and therefore preventing entrance of moisture is the best protective action A protection method called "hot wax dip" is commonly used in automotive industry. In this method faying surfaces that will make crevices are usually painted before assembly.
Faying surface sealing is normally performed simultaneously with the sealing of the fasteners that clamp the joint together. When used in conjunction with a fastener or mechanical part installation specification, this sealing note shall immediately follow the appropriate installation

Allowable gap in between faying surfaces of snug-tightened joints AraEng (Structural) (OP) 10 Apr 17 18:44. We have an HSS beam with end-plate connections (no moments at the ends) that's field modified. As a result the modification, the beam is short and the faying surfaces of one of end-plate connections have 7/16" gap in between them.
