The dyeing defects that take place because an acid permeates out from the
microgrooves and the thread grooves of the anodized product are prevented.
And it is a dyeing pretreatment agent that improves the leveling properties
of the dyeing.

special features

• The spots that take place in the grooves and the microgrooves and the dyeing defects in the shapes of the stars are prevented.
• The stains and the dyeing defects due to the insufficiency of the water are prevented.
• The leveling property is improved.
• The color changes when the dyeing gets small.
• The colorabilities of the alloys, regarding which the uniform dyeing is difficult, are very much enhanced.

points to be cautious about

• Because the deposition for a long time causes the deterioration on the surface, you must be cautious.
• In order to raise the solubility or the stirring effect, it is efficient to carry out the air stirring when dissolving.
• Although the pH when there is the make-up (50g/l) is around 2.0, because the value of the pH gets changed according to the inflows of the acids, the alkalines, etc., there is a need to adjust the pH regularly.
• Although the liquid can become brown according to the changes of the elapsed time, there is no influence on the performance.
