DeSoto PR1440A2PT Fuel Tank Sealant, 1 pt, Liquid, Black

PR-1440 Class A Aircraft Fuel Tank Sealant is a two-part, manganese dioxide-cured polysulfide compound designed for brush application. It provides excellent adhesion to common aircraft substrates and maintains flexible, elastomeric properties after prolonged exposure to jet fuel and aviation gasoline.

WARNING: This product can expose you to chemicals including carbon black, formaldehyde, titanium dioxide and toluene, which are known to the State of California to cause cancer, birth defects or other reproductive harm. For more information, visit www.P65Warnings.ca.gov.

Overview

PR-1440 Class A is an aircraft integral fuel tank sealant designed for brush sealing of fasteners in fuel tanks and for other aircraft fuselage sealing applications.

It has a service temperature range of approximately -65 °F to 250 °F, with intermittent exposure up to approximately 275 °F.

PR-1440 Class A is a two-part, manganese dioxide-cured polysulfide compound. The uncured material is suitable for brush application in thicknesses up to approximately 25 mil.

It cures at room temperature to form a resilient sealant with excellent adhesion to common aircraft substrates and maintains its elastomeric properties after prolonged exposure to jet fuel and aviation gasoline.
