3.2 Local Engineering Specification (LES) CP62-06-RR-1053 specified peroxide activated paint remover, Turco 6881 for use on C-130 aircraft exteriors. Local Engineering Specification CP62-06-RR-1053 Amendment 2 authorized the use of another peroxide based paint remover, B&B 9095, which has been thoroughly evaluated and used successfully for removing paint from other Navy and DoD aircraft exteriors. Based on available test data and successful usage history with other DoD aircraft, B&B 9095 and Turco 6881 paint removers are considered acceptable alternatives for use on C-130 aircraft as specified by procedures in the base document.

Additionally, primary depaint facility at Tinker Air Force Base requested use of the PS-3010 remover per MIL-PRF-32587 due to their waste treatment plant process.

3.3 This revision is being issued to add PS-3010 as an acceptable alternative paint remover.

3.4 This revision constitutes closing action on WMS task number 07174870.

4. Application: This directive applies to all activities removing paint coatings per reference (a), Chapter 4 from exterior metallic surfaces of C-130 aircraft as directed by references (b) or (c).

5. Special Tools and Test Equipment: None.

8. Instructions:

WARNING

The materials and processes specified by this instruction can be hazardous. Observe all safety precautions outlined in the SDS for each chemical including using appropriate Personal Protective Equipment (PPE).

8.1 Comply with the general requirements of reference (a), Chapter 4 for removing paint coatings from exterior metallic aircraft surfaces using chemical paint removers. Comply with additional detailed requirements of references (b) and (c).

8.2 Using approved masking materials as specified in reference (a), Appendix B, mask all openings, non-metallic surfaces (including fiberglass, composites, rubber, plastic surfaces, windows, antennas, radome, etc.), engine intakes, exhaust openings, probes, exposed electrical connectors, bearings, rod ends, wing folds, adhesively, bonded joints, fasteners with rubber seals

8.4 Apply a uniform coating of B&B 9095, Turco 6881, or PS-3010 paint remover to surfaces being stripped by means of non-atomizing spray or brush. Allow paint remover to remain on the surface from 30 minutes to no more than 8 hours. Performance improves as temperature increases. Agitation with a stiff non-metal bristle brush will aid in removal of the finish.

8.5 After the chemical remover appears to have ceased reacting with the coating, or when it has reached the maximum allotted dwell time, remove the chemical paint remover and loosened paint using a squeegee or brush. Water washing may be used to assist with removal of the remaining residue. If water is used, however, allow sufficient time for surfaces to dry before reapplying additional chemical paint remover.

8.6 As necessary, repeat step 8.4 above to remove remaining paint and primer while maintaining a dwell time of no less than 30 minutes and no more than 8 hours. Follow by removing the chemical remover as per step 8.5 above. Chemical remover may be applied a maximum of three times.

WARNING

MIL-PRF-85570 Aircraft Cleaning Compound is irritating to skin and eyes.

Prolonged contact may cause dermatitis. Wear chemical splash proof goggles and gloves. Use only with adequate ventilation. Consult the applicable Safety Data Sheet (SDS) and local Occupational Safety and Health (OSH) regulations for additional information.

8.7 Following removal of paint and primer, clean all affected surfaces with MIL-PRF-85570, Type II, Aircraft Cleaning Compound to remove remaining residue using the methods and materials specified in reference (a), Chapter 2.
