This specification covers the requirements for two types of a two-part, transparent, reversion resistant flexible insulating compound, to provide resilient, environmental, and electrical insulation of components in systems in temperature range 85 to 392 °F (-65 to 200 °C). These insulating compounds are intended for embedding, potting or encapsulation of electrical and electronic components in systems where tear resistance is not critical but their use is not limited to such applications. These transparent compounds allow visual circuit and part identification and facilitates part replacement and repairs. The insulating compound shall cure in sections of unlimited thickness, either exposed to air or completely sealed.
This standard describes the accepted methods used for preparing aerospace sealant test specimens for qualification and quality conformance or acceptance testing. AS5127/1 and AS5127/2 are to be used in conjunction with this document and the applicable AMS specifications.
This SAE Aerospace Standard (AS) describes test methods to determine the application and performance properties of two-component sealing compounds. It shall be used in conjunction with AS5127 and the applicable material specification. When modifications to these test methods are called out in material specifications, the material specification shall take precedence.
This specification covers two-component polysulfide sealing compounds for quick repair of integral fuel tanks and fuel cell cavities. The sealing compound shall be capable of being cured as low as 20 °F (-7 °C), and be resistant to long term exposures from -65 to 250 °F (-54 to 121 °C).
This specification covers one type of one-component, air drying protective 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.
This specification covers a synthetic rubber sealing compound which is electrically conductive when used in a faying surface, contains corrosion inhibitors, and supplied as a two-component system which cures at room temperature, suitable for application by extrusion gun or spatula.
