SAE AMS3278-2004 PDF

Scope: This specification covers polyurethane (PUR) in the form of two-component sealing compounds. This product has been used typically for contact with fuels, but usage is not limited to such applications. Each application should be considered separately. This polyurethane (PUR) has a service temperature range of -65 to +250 degrees F (-54 to 121 degrees C) with a continuous fuel service temperature range of -65 to +160 degrees F (-54 to +71 degrees C). It may be used for faying surface sealing, wet-installation of fasteners, overcoat of fasteners, sealing joints and seams and, in some cases, as a non-structural adhesive. NOTE: The use of an adhesion promoter shall be required to obtain proper adhesion.
