Overview

PR-1005-L is an aircraft integral fuel tank slosh coating designed as a topcoat or barrier coating, cured to resist prolonged exposure to both jet fuel and aviation gas. It has a service temperature range from - 100F (-73C) to 250F (121C), with intermittent excursions up to 275F (135C). PR-1005-L is a one part, synthetic rubber solution.

The uncured material is a thin syrup suitable for application by brush, filland- drain, dip, or spray. It cures at room temp. by the evaporation of solvent to form a smooth, tough, flexible transparent film having excellent adhesion to common aircraft substrates and polysulfide sealants.

Test results are in accordance with MIL-S-4383 specification test methods. Color: Red; Dry time(77F): 20 mins.; non-toxic.

PRC SLOSHING SEALER PR-1005-L PT

June 24, 2023

I am hoping that the sealer works well. It states that it hardens in 20 minutes and in other documentation states that it is fully cured in 48 hours. After waiting 7 days the sealer was still tacky. It may have been because it was thicker in corners etc. and takes longer to dry if it is puddled up in places. So I am going to wait another week before adding fuel to the tank to make sure it is truly cured. I had leaks around rivets that were driving me crazy leaving blue fuel marks under the wing.

Has anybody tried this product in an automotive application yet? I want to seal a transparent plastic fuel cell (polyethylene) to prevent staining from contact absorption. Fuel typically contains ethanol! I see this was asked already- does anybody have an answer yet ? Grtzzz......

Q: Can this be used with auto gas?

Per the vendor, it has not been tested with auto gas. Customers can use at their own risk.

Q: Hi, I'm sealing up a fuel tank with PR1422B1/2 and would like to apply PR1005L over that. How long should I have to wait after applying the 1422 so i can apply the 1005 or should I wait until it is completely cured?

It would be best to wait for the PR1422 material to completely cure before applying any other product over it.

Q: Is this product considered as hazmat for shipping?

We can ship via Fed Ex or UPS Ground within the USA without a hazardous materials fee. All air shipments will be regarded as hazardous goods.

Q: Can this PR-1005-L BUNA-N-SLOSH coating be used with composite fuel tanks?

This is made to work with aluminum tanks and should work on fiberglass tanks as well. This will not work on FRP (fiberglass reinforced plastic) tanks.

Q: Can PR-1005-L Buna-N Slosh Coating be applied to a sealed tank by pouring it inside and thoroughly sloshing it around and then draining it and then letting it dry? How much material would be required for a 26 gallon tank?

This material can be poured in the tank, and sloshed around to coat the inside of the tank, but the manufacturer does not offer an estimated coverage.

Q: Can you paint enamel over PR1005L?

There is no information regarding painting this material when cured, but it is a type of synthetic rubber compound, so refer to the paint manufacturer to determine if that paint will adhere to a synthetic rubber surface.
