Description

Callington CH3003 is a fast environmentally friendly, low odour, acid-activated, thixotropic paint stripper that effectively strips typical aircraft paint/primer systems like polyurethane, epoxies, epoxy primers etc.

Directions for Use

BEFORE STRIPPING:
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 above 20⁰C.
4. Remove all oil and dirt by washing aircraft with a Callington exterior alkaline cleaner (e,g, CH087, CH511C, CH8150HG), or equivalent, before stripping. Rinse the surface with water to ensure it is clean and free of alkaline residue before treating with a stripper.
5. Allow surface to completely dry before stripping.
6. Before applying the stripper, mask or cover any sensitive areas that may be damaged by CH3003 for example: rubber, composite parts, landing gear, windows, seals, electronics, high strength steel, magnesium, cadmium plated steel 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. Best results will be obtained if the paint surface is sanded before application.

STRIPPING PROCEDURE:
1. Spray or brush CH3003 onto the surface to be stripped.
2. Apply an even coat of CH3003, 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 4mil in thickness, apply product to approximately 8mil of thickness.
3. Pay close attention to directing the product into areas where the panels overlap.
4. Keep the surface wet with CH3003 until the paint starts to buckle.
5. Allow for sufficient contact time depending on the ambient temperature, humidity, paint system and thickness of paint to be stripped (typically 1 – 3 hours, or longer for tough coatings).
6. When the paint is starting to lift, apply compressed air to, or use a brush on, the surface to remove any loose paint.
7. Reapply CH3003 paint stripper to leftover painted areas as required. Avoid application to bare metal surfaces.
8. When all paint is lifted, agitate the surface to remove all loosened paint and any residual stripper.

AFTER STRIPPING:
1. 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.
2. Apply an alkaline cleaning solution (e.g. CH087, CH511C, CH8150HG), to effectively remove any contaminants or paint stripper residue.
3. Finally, rinse the surface with high pressure water to ensure all traces of acid and cleaning solution have been removed.

SUITABLE EQUIPMENT
CH3003 can be used with suitable spray pumps, for example a high pressure (5:1 or 10:1) air activated spray pump, coupled with high pressure hose and spray wand, using a fan size tip nozzle. For more information, please call your nearest Callington representative.
