Easy-to-use 3M Aerospace AC-360 B-1/2 gray fuel tank and fuselage sealant from SkyGeek is made for integral fuel tank and fuselage sealing tasks. Add a protective coating to your aircraft during both manufacturing and maintenance. The mixed thixotropic paste compound is made up of a manganese dioxide-cured polysulfide formula. Easily apply the fuel tank and fuselage sealant by injection gun or spatula. Aviation fuels, petroleum products and chemicals often used in the aviation industry are effectively blocked by this cured sealant. More sealant purchase volume and reduced need for rework from shrinkage are provided by a solvent-free formula. AC-360 also features a fifteen percent reduction in added weight over conventional fuel tank sealants in order to increase bond strength on metal, composite and coated substrates.

Mixing Instructions

Two Part Sealant: 1. Holding the cartridge, grasp the dasher rod and pull back approximately one inch.

2. Insert the ramrod into the hollow of the dasher rod, break the piston loose, and inject about 1/3 of the contents into the cartridge.

Note: Do not inject all of the catalyst in one location. Distribute evenly throughout base material.

3. Repeat steps 2 and 3 until all the contents of the rod are emptied into the cartridge. Remove the ramrod.

4. Mix for the required number of strokes (hand mixing) or for the required amount of time (machine mixing) indicated in the kit intructions.

5. When mixing is complete, remove bottom cap.

6. Pull the dasher rod back to the neck of the cartridge, grasp the cartridge firmly at the neck, unscrew the dasher rod and remove.

7. Screw the nozzle into the cartridge, insert into the extrusion gun and use as required. For hand extrusion, press the used dasher rod against the plunger to force the material from the cartridge.


The shelf life of AC-360 is 6 months from date of packaging, when stored at temperatures below 80 degrees F in its original container.

Mixed AC-350 Class B may be stored under refrigeration as follows: 15 days at -10 degrees F, 30 days at -40 degrees F. It is important to remember that freezing, storing and thawing procedures reduce application life. Also, frozen storage will reduce application life by varying amounts depending on the storage temperature and length of storage time. All aspects of storage, freezing and thawing should be planned carefully and it is not recommended to mix and freeze with less than 1/2 hour application time.

Health and Safety Precautions

AC-360 sealant is safe to use and apply when recommended precautions are followed. Before using this product, read and understand the Material Safety Data Sheet (MSDS), which provides information on health, physical and environmental hazards, handling precautions and first aid recommendations. An MSDS is available upon request. Avoid overexposure. Obtain medical care in case of extreme overexposure.

Typical Physical and Application Properties

  • Color: Base - Off White, Accelerator - Brown, Mixed - Dark Gray

  • Mix Ratio: 100 base / 10 accelerator (by weight)

  • Nonvolatile Content: 98%

  • Base Viscosity (RVF Brookfield #7 Spindle @ 2rpm, 77 degrees F): 7,500 - 11,000 poise
  • Application Life and Cure Time
    (At 75 degrees F, 50% Relative Humidity)


  • Minimum Application Life*: 30 minutes

  • Typical Tack-Free Time**: 2 - 3 hours

  • Typical Cure Time***: 2 - 3 hours
  • B-2

  • Minimum Application Life*: 2 hours

  • Typical Tack-Free Time**: 8 hours

  • Typical Cure Time***: 8 hours
  • *Application life refers to the length of time that mixed compound remains at a consistency suitable for application with spatula or caulking gun. Application life is always measured at a standard temperature of 77 degrees F with a relative humidity of 50%. In general, for every 20 degree rise in temperature, the application life is halved; and for every 20 degree drop, it is doubled. High humidity levels during the mixing process will shorten application life.

    **Tack-free time is the length of time after which a mixed sealant will no longer tightly adhere to LP-P-690 standard low-density polyethylene film.

    ***Cure time is defined as the length of time it takes AC-360 sealant to reach 30A hardness. It depends on three factors: remaining application life, temperature and relative humidity. The temperature/humidity factors for application life also apply to curing. To accelerate the curing process, apply heat up to (but no more than) 140 degrees F.
