Procedure

1. SUBTASK 70-11-64-110-001 Local Removal Of Silicone Rubber

   1. Use a razor or a sharp plastic scraper to cut away most of the RTV silicone rubber from areas where the RTV silicone rubber that you must remove is thick.

   2. Stir (mix) the CoMat 01-586 REMOVER, RTV SILICONE RUBBER with a clean spatula or other clean stirring stick, to fully mix the gel.

   3. Apply an approximately 0.5 in. (13 mm) thick layer of CoMat 01-586 REMOVER, RTV SILICONE RUBBER to the RTV silicone rubber that you must remove.

      1. Keep the CoMat 01-586 REMOVER, RTV SILICONE RUBBER on the area for 15 - 45 minutes to degrade (cause deterioration of) the RTV silicone rubber.

         NOTE

         Water will stop the effect of CoMat 01-586 REMOVER, RTV SILICONE RUBBER.

      2. Do not let water touch the gel layer until it is time to remove the gel from the part.

   4. Remove the degraded RTV silicone rubber. Use one of the procedures in the subsequent list:

      1. Pressure Flush Procedure

         1. Use an air-assisted pressure spray gun to flush the part with clean water.

      2. Brush Procedure

         1. Use a soft bristle brush with warm water or an SPM TASK 70-11-26-300-503 solvent, to remove the degraded RTV silicone rubber.

         2. Flush the area fully with clean cold water to remove all remaining CoMat 01-586 REMOVER, RTV SILICONE RUBBER.

   5. Do an inspection of the area for remaining RTV silicone rubber. If the area shows remaining RTV silicone rubber, it is permitted to do this task a second time on that area.

      1. For each area on which you do this task, it is permitted to do this task a total of two times maximum during each shop visit.

   6. Use one of the procedures in the subsequent list to dry the part:

      NOTE

      If the water on the part does not flash off after the part comes out of the hot water, then the time interval that the part stayed in the hot water was too short.

      1. Hot Water Flash Dry Procedure

         1. Put the part fully in hot water at 150 - 200 degrees F (66 - 93 degrees C) until the part is sufficiently hot to flash dry, then remove the part from the hot water.

      2. Blow Dry Procedure

         1. Use clean air to blow the water off the part.

   7. Dry the part with clean air if there is remaining water on the part.
