Product Code:SAE AMS3726/3
Title:Shims, Filled Resin Compound Liquid Precatalyzed
Issuing Committee:Ams P Polymeric Materials Committee
Scope:This specification covers a filled, resinous, thermosetting, precatalyzed, liquid compound capable of being applied and cured in place between the surfaces of mechanically fastened (joined) structures. This product has been used typically as a molded shim during assembly of aircraft components and parts, but usage is not limited to such applications. The compound covered by this detail specification requires storage in the frozen condition just prior to installation.
