Aluminium Pretreatment Process
The most popular method for preventing corrosion in items composed of aluminium and its alloy is the chemically applied conversion coating method. It is common knowledge that aluminium products oxidize, leaving a thin film of aluminium oxide on the surface. This oxide layer is also left behind during the anodizing process under the influence of an electric current. Therefore, before painting, it needs to be removed. In addition to this, aluminium may have oil on the surface from the fabrication or shaping process, which must also be cleaned
Phosphating sequence process for extruded aluminium
Keeping your aluminium safe and long lasting
It react with extruded aluminium and removes the foreign particles viz. fatty acids & oxide layers from the outer surface. It is very easy to use and it works very efficiently in room temperature . Degreaser-AL is acidic in nature.
Alchrome-AL 250 is a anti corrosion & chromatising agent for extruded aluminium & die cast aluminium. It gives a golden yellow chromatising film over aluminium surface. It protect aluminium surface from white rust & oxide films.
Zr Chrome-AL 200
It is a zirconium based chromating agent for aluminium. It is RoHS compliant chemical . It gives transparent blue coating. It protect aluminium from further oxidation & also increases the powder coating durability.
De-Fat-AL 58 is a non caustic but silicate based degreasing agent. Due to its low alkalinity level it removes oil & fatty acids from aluminium alloys.
