PPG Aerospace® PR-1428 A-2 Removable Access Door Sealant from SkyGeek offers a reliable, yet temporary bond that is easily removed when access is needed. The sealant is designed to hold access doors in place, allowing them to be removed when needed for maintenance or repairs. The sealant has a vibrant red color for visibility and is slightly elastic to ensure a strong bond in the face of vibrational forces. Use PPG Aerospace® PR-1428 A-2 Removable Access Door Sealant as an access door sealant or in the fabrication of form-in-place gaskets.
PPG Aerospace® PR-1428 A-2 Removable Access Door Sealant is reliable and has a service temperature range of -65°F (-54°C) to 250°F (121°C), with intermittent excursions up to 275°F (135°C). That means you'll enjoy a better bond no matter what type of environment you're flying in. The sealant is a two-part, manganese dioxide-cured polysulfide compound that is designed to be applied by brush in thicknesses up to 25 mils. The door sealant cures at room temperature and is removable when applied to common aircraft substrates like aluminum and composite.
