PR-2001 Class A is a rapid cure, low odor, aircraft integral fuel
tank sealant. It has a service temperature range from -80°F
(-62°C) to 320°F (160°C), with intermittent excursions up to
420°F (216°C). This material is designed for brush sealing
of fasteners in fuel tanks and other aircraft fuselage sealing
applications. The cured sealant maintains excellent
elastomeric properties after prolonged exposure to both jet
fuel and aviation gas.
PR-2001 Class A is a two-part, epoxy cured PERMAPOL® P-3.1
polythioether compound. The uncured material is suitable for
application by brush in thickness up to 25 mils. It cures at room
temperature to form a resilient sealant having excellent
adhesion to common aircraft substrates.
