A good access door sealant has to walk the fine line between offering a reliable hold and still allowing access when needed. PPG Aerospace® PR-1428 B-1/2 Access Door Sealant from SkyGeek strikes the perfect balance and is a low-adhesive sealant with a wide service temperature range and plenty of power. PPG Aerospace® PR-1428 B-1/2 Access Door Sealant works in temperatures ranging from -65°F (-54°C) to 250°F (121°C), and can also withstand temperatures as high as 260°F (135°C). Use it to temporarily seal access doors shut or for making form-in-place gaskets. The sealant can also be used to protect electrical wires, terminals and equipment against fuel moisture, dirt and short circuits.
PPG Aerospace® PR-1428 B-1/2 Access Door Sealant from SkyGeek is a two-component sealant that should be mixed just before use. The manganese dioxide-cured polysulfide compound has low sag and a thixotropic texture that is ideal for application by extrusion gun or spatula. The sealant cures at room temperature and is removable when needed. PPG Aerospace® PR-1428 B-1/2 Access Door Sealant adheres to most common aircraft substrates.
