Pretreatment for Aluminium Process

Degreasing

Alkaline Degreaser :-

Removal of oil grease & oxide layer from aluminium surface. Metal cleaner DGA-110 is alkaline base degreaser. This powder form degrease used for deep application. Alkaline series of chemical are very useful for aluminium alloys.

Acidic Degreaser :-

This chemical is very effective for remove oil, grease & oxide layer. Metal cleaner ALC-12 used for aluminium materials. In this process is not necessary deoxide process.

Chromatising

Chromatising is used to chemically convert the surface of the aluminium product. This result in a thin oxide layer what is referred to conversion layer during the chromatising a surface layer result which varies in colour from white to golden/green. Chromatising is often in applied as coating pretreatment - as it provide high quality adhesion an excellent production against corrosion. Metal cleaner CHROME-26 is used for golden/yellow colour. Metal cleaner CHROME-28 is used for green colour.
