Ardrox 1074
Etch, corrosion remover and brightener for aluminium
ARDROX 1074 is an aqueous acidic product containing solvents and surfactants.
This product is primarily intended as an application cleaner for aluminium. It will remove tarnish, oxide
films and light oil and leave a slightly etched surface. ARDROX 1074 is suitable for the pre-treatment of
aircraft and transport vehicle bodies prior to painting or the application of other protective systems such
as chromate conversion coatings. It is useful as a treatment prior to spot welding or adhesive bonding of
aluminium.
Method of use :
- ARDROX 1074 is used at ambient temperature, diluted with water, and may be applied to aluminium
surfaces by brush, spray or immersion. If the surface is obviously soiled, a pre-cleaning operation should
be carried out with a detergent cleaner e.g. ARDROX 6025.
- The degree of dilution and contact time will depend on the nature of the adherent deposits and the
amounts of etch required. Dilutions will normally range from 1 part by volume product plus 1 part by
volume water to 1 part by volume product plus 3 parts by volume water. Contact times will normally
range from 3 to 30 minutes.
- Scrubbing the surface with a soft brush will assist the complete removal of any adherent deposits. On
vertical surfaces it is best to apply the material from the bottom upward to prevent streaks caused by
small amounts of product running over the untreated surface. Finally thorough rinsing with water should
follow the etching operation.
