Product Code:SAE AMS3697
Title:Aerodynamic Fairing Compound, -55 to +150Mdc (-65 to +300Mdf)
Issuing Committee:Ams G9 Aerospace Sealing Committee
Scope:This specification covers a two-component air-curing, aluminum-powder -filled, epoxy-resin-base material in the form of a paste or putty, suitable for application by spatula or putty-knife. Primarily for filling small holes, crevices, and gaps or for smoothing areas requiring thin layers of material to produce the required smoothness on aerodynamic surfaces subject to service temperatures from -55 to +150 degrees C (-65 to +300 degrees F).
