Details
Document Number: AMS3278A
Revision Number: A
Title
Sealing and Coating Compound: Polyurethane (PUR), Fuel Resistant, High Tensile Strength / Elongation, For Integral Fuel Tanks / Fuel Cavities / General Purpose
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 °F (-54 to 121 °C) with a continuous fuel service temperature range of -65 to +160 °F (-54 to +71 °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.
