The compounds covered by this specification are used in the production and maintenance of military aircraft exposed for prolonged periods to extreme seagoing environments not encountered by civilian aircraft (see 3.3.2.3 and 4.8.9). Peel strength (see 3.3.2.8) requires immersion in Military fluids. Only compounds identified on the Qualified Products List are used because of the repairability requirement (see 3.3.2.10). The intended use of sealing compounds covered by this specification are for sealing interior and exterior areas on weapons and aircraft systems to protect metal components against corrosion within a service temperature range of −65° to +320° F (−54°C to +160° C) with intermittent use to +400° F (+205°C) depending on the Class of compound selected. The sealing compounds are not intended for use as integral fuel tank sealants.
