Approvals: Airbus CML 09ABB1 Boeing D6-17487 (conformance)
Concentration
Ardrox® 2872 is ready for use as supplied.
Preparation
Prior to the application of Ardrox® 2872, any surface materials requiring masking should be accommodated. Consult your OEM or internal documentation for the appropriate masking procedures. Best results will be achieved at temperatures over 20 °C (68 °F). The paint surface should be clean and dry.
Application
Ardrox® 2872 is applied by spraying with a piston-type pump and spray wand. Use with 2:1, 3:1, 5:1 or 10:1 pumps (5:1 and 10:1 preferred). Pouring is also possible.
Apply to a thickness of 2 to 3 times the coating thickness or until the paint is uniformly covered. Do not apply too heavily, sagging could occur. Personnel should always wear suitable protective clothing.
Paint removal
In general, Ardrox® 2872 should remain on the surface for 2 to 6 hours (depending on temperature, coating thickness and type, and other conditions). If necessary to bubble the paint, Ardrox® 2872 can be left on the surface for longer periods of time.
Note: Ardrox® 2872 is designed for a single-coat application and so does not require removal and reapplication in order to expedite removal

Elimination
Ardrox® 2872 and bubbled paint can be removed with a squeegee, brush, rinsing with water, or equivalent method. Do not allow the softened paint to dry out as it may re-adhere to the primer coat. Be aware that the upper coat and the intermediate coat are removed, while the primer in contact with the substrate remains intact.
Spot reapply the stripper to remaining painted areas if necessary and repeat the removal method. Follow up with a final rinse or wipe using water or wash with Ardrox® 6484A or similar.
Pre-trial
Pour or spray Ardrox® 2872 on a vertical portion of the aircraft or panel. Record the coating thickness, time and temperature at application.
