To restore to the base metal surface, the paint stripper must break the coating’s molecular bond to let the paint residues drop harmlessly away and leave the alloy untouched. This is particularly important for light alloys such as magnesium, which is very sensitive to acid and alkaline solutions.
The typical stripping process for aluminium will involve immersion in a proprietary stripping solution (not available for separate sale) to first remove the paint/powder.
Stripping is always followed by hot water- blasting to remove all traces of the metal’s coating and of the stripping solution.
All alloys require pre-treatment to enable a coating system to adhere to the base metal. The pre-treatment may be chemical (e.g. chromate) or the application of an etch primer.
Our system effectively removes all pre-treatments back to mill finish with absolutely no profile damage.
