    5、ed 2015-07 Superseding AMS-S-4383A Sealing Compound, Topcoat, Fuel Tank Buna-N Type RATIONALE AMS-S-4383 Rev B incorporates changes to film thickness, non-volatile content (NVC), viscosity, and color leaching requirements (based on requirement for use of oil-soluble dye). These minor changes are bas

    6、ed on input from all qualified product manufacturers and do not change the form, fit, or function of the sealant as currently employed. Widening the NVC envelope was formally approved when the specification was MIL-S-4383 but the change was never incorporated. Allowance for use of alternative dry fi

    7、lm thickness measurement equipment has also been included. As one-component material, batch and lot are the same so Acceptance Tests are run only once consistent with other one-component sealant specifications. 1.

    8、ive coating which cures at room temperature. The topcoat compound covered by this specification shall be formulated from butadiene acrylonitrile copolymer and shall be colored red by the use of an oil soluble dye. 1.2 Application This material is a one part compound designed as topcoat or barrier co

    9、ating for integral fuel tank sealants and coatings but usage is not limited to such applications. It may also be used for temporary repair of aircraft fuel tanks using a “fill-and-drain” technique. It may also be used as a bonding agent for materials such as synthetic rubber metals, glass, and many

    10、plastics. 1.2.1 Notice The cured coating is resistant to exposure from both jet fuel and aviation gas; it is not suitable for use with motor fuels containing alcohols. 1.3 Safety Hazardous Materials Shall be in accordance with AS5502 (1.1). 2.

    41、-S-4383B Page 7 of 9 4.6 Test Procedures Standard Test methods are in accordance with AS5127 and AS5127/1. In the event of a conflict between the text of this document and AS5127 and/or AS5127/1, the text of this document takes precedence. 4.6.1 Tack Free Time A coat of the topcoat compound shall be

    42、 applied to a 0.032 x 1 x 6 inch (0.8 x 25 x 152 mm) bare metal panel conforming to AMS4049 and to a panel which has been coated with a polysulfide sealing compound qualified to AMS-S-8802 and cured in accordance with manufacturers instructions. The coated panels shall then be suspended from a suita

    43、ble rack at standard conditions for 4 hours. A 1 x 7 inch (25 x 178 mm) strip of low density polyethylene film (ASTM D4976 or equivalent) 0.005 inch 0.002 (0.13 mm 0.05) thick shall be applied to the topcoat compound and held in place at a pressure of approximately 0.5 ounce per square inch (0.0002

    44、N/mm2) for 2 minutes 10 seconds. The strips shall then be slowly and evenly peeled back at right angles to the topcoat compound surface. The polyethylene film shall come away clean and free of topcoat compound. 4.6.2 Low Temperature Flexibility Six AMS4049 aluminum panels, measuring 0.020 x 1 x 6 in

    45、ch (0.51 x 25 x 152 mm), shall be used for this test. Four of the panels shall be coated with a polysulfide sealant compound qualified to AMS-S-8802 and cured in accordance with manufacturers instructions. The cured thickness of the polysulfide sealing compound shall be 0.125 inch (3.17 mm). Two of

    46、these coated panels and the two bare panels shall be coated with the topcoat compound and cured in accordance with 4.5.4. All six panels shall then be immersed for 48 hours at 120 F (49 C) in test fluid conforming to ASTM D471, Reference Fuel B. After conditioning, the panels shall be tested in acco

    47、rdance with AS5127/1 (7.6). The two panels coated with polysulfide sealant, which were not topcoated, shall be considered as control panels to insure that any failure is not due to failure in the polysulfide sealing compound. 4.6.3 Resistance to Heat Six AMS4049 aluminum panels, measuring 0.032 x 1

    48、x 6 inch (0.8 x 25 x 152 mm), shall be used for this test. Four parallel fillets, measuring 0.19 x 0.5 x 2 inch (4.8 x 13 x 51 mm), of polysulfide sealant compound qualified to AMS-S-8802 and cured in accordance with manufacturers instructions shall be applied to each panel. Two of these panels and the two bare panels shall be coated with the topcoat compou
