PR1750B2-60Z Corrosion Inhibitive Sealant, 6OZ, 654, AMS3276

PR-1750 Class B-2 is a two-part, manganese dioxide-cured polysulfide aircraft fuel tank sealant designed for integral fuel tanks and fuselage sealing applications. It provides excellent resistance to jet fuel and aviation gasoline and cures at room temperature to form a resilient seal with strong adhesion to common aircraft substrates.

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

Overview

PR-1750 Class B is an aircraft integral fuel tank sealant designed for fillet sealing of fuel tanks and other aircraft fuselage sealing applications.

It has a service temperature range of -65°F (-54°C) to 250°F (121°C), with intermittent exposure up to 360°F (182°C).

The cured sealant maintains excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gasoline.

PR-1750 Class B is a two-part, manganese dioxide-cured polysulfide compound. The uncured material is a low-sag, thixotropic paste suitable for application by extrusion gun or spatula. It cures at room temperature to form a resilient sealant with excellent adhesion to common aircraft substrates.
