Details
Document Number: AMS3258A
Revision Number: A
Title
Sealing Compound, Polythioether For Aircraft Windshields and Canopies, For Use Up to 300°F (149°C)
Scope
This specification covers a polythioether based sealing compound supplied as a two-component system suitable for application by brush, or by extrusion gun or spatula.

This production has been used typically for sealing aircraft windshields and canopies. This includes both sealing between the windshield/canopy and the aircraft structure for pressure sealing, and sealing around the windshield/canopy for weather sealing, but usage is not limited to such applications. The sealing compound cures at room temperature and may have an accelerated cure at higher temperatures. The sealing compounds are usable from -65 to 300 degrees F (-54 to 149 degrees C).
