Sealing Compound

Aerospace adhesive standards are applicable to the use of adhesive and sealant materials in aerospace vehicles. These standards address the preparation of sealant material specifications and aerospace recommended practices for sealing processes and related activities. For example: the sealing of integral fuel tanks. SAE International (SAE) has several technical committees (.doc download) that contribute to the development of aerospace adhesive standards. These standards are related to sealing compounds in an aerospace application.

SAE AMS 3267/1A-2003 (SAE AMS3267/1A-2003)

Sealing Compound, Low Adhesion, Corrosion Inhibiting, 200 to 600 Poises (20 to 60 Pa?s), 1/2 Hour Application Time (A-1/2) (Cancelled: Apr 2003)

This specification covers accelerated curing synthetic rubber compounds with corrosion inhibitors and low adhesive strength supplied as a two-component system. This product has been used typically for sealing aircraft access doors and accessories where gaskets are required, but usage is not limited to such applications. Compound is classified as an A-1/2 sealing compound; the compound being suitable for brush application with a minimum application time of 1/2 hours after the start of mixing.
