Additive to reduce total friction coefficient for trivalent chromium passivation
METASU YFA-L is an additive formulated to reduce the total friction coefficient when added to a trivalent chromium passivation agent.
The corrosion resistance and wastewater treatment of the trivalent chromated coating are not affected.
- The total friction coefficient can be lowered by direct addition to the trivalent chromium passivation agent.
- Corrosion resistance and wastewater treatment are not affected.
- The surface may take on a slightly darker tone as compared to normal processing.
|Appearance||Reddish-brown slightly turbid liquid|
|Chemicals used||Addition amount|
|METASU YFA-L||0.3 – 5ml/L|
The total friction coefficient decreases with the addition of METASU YFA-L, and converges to a constant value in the end.
There is no noticeable change in the value with further amounts added.
|Chemicals used||Replenishment reference (standard)|
|METASU YFA-L||0.5 – 1.0ml/100dm2|
Verify before addition as replenishment amount differs for each line.
