Access doors have special requirements when it comes to sealant. You need an aircraft sealant that’s strong enough to keep moisture out during normal flight conditions, but not so strong that you can't still access your aircraft when you want to. PPG Aerospace® PR-1428 B-2 Access Door Sealant offers the perfect combination of strength and flexibility, sealing access doors, but still allowing for easy access should the need arise. The sealant is dark red for improved visibility and because it is a thixotropic paste, it can be applied using an extrusion gun or spatula.
PPG Aerospace® PR-1428 B-2 MIL-S-8784B Access Door Sealant is a low adhesive sealant that is designed for access doors, but can also be used for form-in-place gaskets, to protect electrical wires, sealing terminals and for protecting equipment against fuel, moisture, dirt and short circuits. The class B, two-part manganese-dioxide-cured polysulfide sealant cures at room temperature and bonds well to most aircraft substrates. The sealant is sold in a 2-part, pint-size kit.
