Description

Callington CH9004 is a low odour, non-toxic, hydrogen-peroxide activated, environmentally friendly thixotropic paint stripper that effectively strips typical aircraft paint/primer systems like polyurethane, epoxies, epoxy primers etc.

Application

1. Thoroughly clean all paint stripping equipment (spray guns, pots, pumps and pressure hoses, etc.) per the equipment manufacturer’s recommendations.

2. Use a dedicated pump when applying stripper to aircraft.

3. Optimum results are achieved if hangar temperature is between 25⁰C and 30⁰C.

4. Remove all oil and dirt by washing aircraft with a Callington exterior alkaline cleaner (e,g, CH087, CH511C, CH8150HG), or equivalent, before stripping.

5. Rinse the surface with water to ensure it is clean and free of alkaline residue before treating with a stripper. Allow surface to completely dry before stripping.

6. Before applying the stripper, cover any sensitive areas like electronics, composites, magnesium or plastics. This must be done in accordance with standard aeronautical specifications and requirements of acid strippers detailed in the plane type OEM manuals.

7. Spray or brush CH9004 onto surface to be stripped.

8. Spray Application: Spray an even, medium coat of CH9004, starting from the bottom of the aircraft and working upward. The recommended thickness of application is two times the thickness of the paint coat, for example if the paint coat is 4mils in thickness, apply product to approximately 8mils of thickness.

9. Keep the surface wet with CH9004 until the paint starts to buckle.

10. Allow for sufficient contact time (2-9 hours or more) depending on the ambient temperature, paint system and thickness of paint to be stripped. Reapply CH9004 paint stripper as required.

11. When the paint is starting to lift, agitate the surface area to remove any loose paint.

12. Reapply CH9004 paint stripper to leftover painted areas as required. Avoid application to bare metal surfaces.

13. When all paint is lifted, agitate the surface to remove the loosened paint and any residual stripper.

14. After finishing the stripping process, collect stripper and paint residue into clean plastic waste bins for disposal as solid waste according to local trade waste regulations.

15. Apply an alkaline cleaning solution (e.g. CH087, CH511C, CH8150HG), to effectively remove any left over paint or paint stripper residue.

16. Finally, rinse the surface with high pressure water to ensure all traces of stripper and cleaning solution have been removed.

SUITABLE EQUIPMENT
CH9004 is best used with high pressure (5:1 or 10:1) air activated spray pumps, coupled with high pressure hose and spray wand, using a fan size tip nozzle.
