Description:

P/S 890 Class B is an aircraft integral fuel tank sealant. It has a service temperature range from - 65°F (-54°C) to 250°F (121°C), with intermittent excursions up to 275°F (135°C). This material is designed for fillet sealing of 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.

P/S 890 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 having excellent adhesion to common aircraft substrates.

Q+A:

Can this Pro-Seal be used on plastic gas tanks?
Per our tech: This a tricky one. The manufacturer doesn't recommend it, but builders have used it as a sealant for fuel probes and gaskets for years. The manufacturer doesn't have any lab tests to show how well it works or doesn't work on plastic, so they will not recommend it.

What is the working time of this Pro-Seal sealant? I need something that has a 2 hour work time.
Part # 09-38560 has a 2 hour work time, 64 hr tack free time, and 112 hr cure time. Variations in temperature and humidity can affect cure time.

Can Pro-Seal be used for fiberglass tanks?
The manufacturer has not tested this material on fiberglass, so they can not guarantee how well it will adhere, but in general, if the surface is contamination free and has a smooth surface, it will adhere. We suggest contacting whoever made the tank, and ask their suggestion for sealing cracks, or pin holes, in the tank.

Can I use ProSeal to seal an oil tank for a race car?
The manufacturer does not list any tests for oil, but it should work fine for pin holes and sealing around rivets on aluminum tanks.

Is this Pro-seal a Type I Class B sealant?
It is a Class II Type B2 sealant

Is this Pro-Seal sealant resistant to ethanol?
Over the years it has been used in applications with ethanol, but there are no lab tests or certs to show it will work.

Is this product Proseal 1425? Can it be used to seal plexiglass windows to aircraft frames?
No. This product is not the PPG PR1425, but we do have a 3M AC-251 window and canopy sealant part number 09-04008 that should work for your application.
