1) n plus D400 Cr (Aluminium Yellow Chromate Powder)
 It builds a thin yellow layer on metal surfaces by providing surface passivation of aluminium and aluminium alloys. It is used at room temperature.

2) n plus D420 Cr (Aluminium Yellow Chromate 1.Component)
     n plus D421 Cr (Aluminium Yellow Chromate 2.Component)
 It builds a thin yellow layer on metal surfaces by providing surface passivation of aluminium and aluminium alloys. It is used at room temperature. The performance of this mixture prepared with these two components is high.
