WARNING

IT IS THE RESPONSIBILITY OF THE OPERATOR TO OBTAIN AND OBSERVE THE MANUFACTURERS MATERIAL SAFETY DATA SHEETS FOR CONSUMABLE MATERIALS INFORMATION SUCH AS, HAZARDOUS INGREDIENTS, PHYSICAL/CHEMICAL CHARACTERISTICS, FIRE, EXPLOSION, REACTIVITY, HEALTH HAZARD DATA, PRECAUTIONS FOR SAFE HANDLING, USE AND CONTROL MEASURES AND ALSO TO TAKE LOCAL REGULATIONS INTO CONSIDERATION.

Procedure

1. SUBTASK 70-38-27-380-001 Application of Dry Film Lubricants

   1. Strip old compound from part with the SPM TASK 70-12-08-300-503 or TASK 70-12-07-120-501. Clean part and prepare surface as directed for each part. If no surface is necessary to be prepared, then none will be specified.

   2. Clean the surface to which you will apply the dry film lubricant. Refer to SPM TASK 70-11-26-300-503.

      NOTE

      Shelf life is one year from date of shipment when the compound is kept in the initial sealed container.

   3. Do a check of the shelf life of the CoMat 06-078 COMPOUND, ANTIGALLING.

      NOTE

      The solids in the CoMat 06-078 COMPOUND, ANTIGALLING usually fall to the bottom of the container quickly. The compound must be fully mixed immediately before and while it is applied to make sure that the solids do not fall to the bottom again.

      It is not necessary to add solvent to make the CoMat 06-078 COMPOUND, ANTIGALLING more liquid.

   4. Mix the CoMat 06-078 COMPOUND, ANTIGALLING fully before you remove the necessary quantity of compound from the initial container.

      NOTE

      Parts can have the temperature increased to 200 deg F (93 deg C) maximum to help the compound to be applied.

   5. Apply CoMat 06-078 COMPOUND, ANTIGALLING to part by one of the subsequent procedures to get a sufficient thickness such that the base metal does not show through the compound layer.

      1. Procedure A: Apply one layer of fully mixed compound with an applicable brush or swab to the specified surface on the part. Make sure that the compound continues to be fully mixed during this procedure.

      2. Procedure B: Put nuts and bolts fully into a good mixed solution of CoMat 06-078 COMPOUND, ANTIGALLING to apply a layer to cover the areas necessary on small hardware items. Make sure that the compound continues to be fully mixed during this procedure.

      3. Procedure C: Apply layer to parts by spraying a good mixed solution of CoMat 06-078 COMPOUND, ANTIGALLING by the use of an airbrush or paint sprayer. Make sure that the compound continues to be fully mixed during this procedure.

   6. The applied layer must be smooth, continuous, constant in color and gloss, hard, tough, and show no bubbles, craters, pin holes, wrinkles, drips, runs, sags, or other surface defects.

   7. 
      CAUTION
      IF YOU TOUCH COATED SURFACES BEFORE YOU CURE THE DRY FILM LUBRICANT, YOU CAN DAMAGE THE DRY FILM LUBRICANT LAYER.

      Cure the applied dry film lubricant compound. Use one of the subsequent procedures that follow:

      1. Cure by air drying at room temperature for at least 18 hours.

         1. After the first 30 minutes of air drying, parts can be touched.

         2. Longer drying, up to 72 hours, can give a better cure.

      2. For titanium alloy parts that do not have adhesive bonds or composite components, dry in air for 30 minutes minimum, then do one of the subsequent procedures:

         1. Bake at 500 deg F - 550 deg F (260 deg C - 288 deg C) for 30 minutes, minimum.

         2. Bake at 425 deg F - 475 deg F (218 deg C - 246 deg C) for 60 minutes, minimum.

         3. Bake at 125 deg F - 175 deg F (52 deg C - 79 deg C) for 120 minutes, minimum.

         4. Bake at 125 deg F - 175 deg F (52 deg C - 79 deg C) for 2 - 2.5 hours, then bake at 375 deg F - 425 deg F (191 deg C - 218 deg C) for 2 - 2.5 hours.

   8. The dry film lubricant coating after cure can look soft, powdery, and easy to damage. This is the normal look of the film and it is necessary to be careful when you assemble the coated parts.

   9. When necessary for fitting functions, use a cloth or equivalent to remove dry film lubricant material that is more than necessary from the coated surfaces of mating parts.

      1. Do not use abrasives.

      2. Be sure that you do not remove too much dry film lubricant. The base metal must not show through the dry film lubricant.
