Treat aluminium from cleaning to a sealed finish.
Aluminium finishing chemicals for every step of the line: cleaning, etching, brightening, deoxidizing, anodizing, conversion coating, colouring and sealing.
Products
We supply the chemicals for these processes; series names and technical data are shared per application.
Cleaners
Cleaners that remove oils, greases and shop soils from aluminium before etching or anodizing.
Etches
Etching solutions that remove the natural oxide and a thin metal layer, giving aluminium an even matt surface.
Brighteners
Chemical brightening baths that smooth the aluminium surface for a bright, reflective finish.
Acid deoxidizing
Acid solutions that remove oxides and the smut left by etching, leaving a clean, active surface.
Anodizing
Electrolytes that grow a controlled, porous oxide layer on aluminium for protection and as a base for colour.
Conversion coatings
Thin conversion layers formed on aluminium that protect the surface and support the adhesion of paint and powder.
Coloring
Dyes and electrolytic colouring processes that colour the porous anodic layer before it is sealed.
Sealers
Sealers that close the pores of the anodic layer, fixing the colour and improving its resistance to staining and corrosion.
