STRUB Non-ferrous metal inhibitor No. 6

Art.-No. 31012

Description
STRUB Non-Ferrous Metal Inhibitor No. 6 is a highly active nonferrous metal inhibitor as an additive for all water-miscible cooling lubricants. It is effective for copper, copper alloys and other metals to prevent the characteristic tarnishing colors of brass alloys.

Application
STRUB Non-ferrous Metal Inhibitor No. 6 is particularly suitable for the post-inhibition of aqueous cooling lubricant systems. The non-ferrous metal inhibitor is completely water-soluble, highly active and effective even at low concentrations. If a higher concentration of free copper ions is present, the addition of the non-ferrous metal inhibitor can lead to increased formation of so-called hydroxide slimes. It should therefore be noted that the filter system may be impaired for a short time.

Dosage
STRUB Non-ferrous Metal Inhibitor No. 6 should be added in a concentration of 0.01 - 0.03%, based on the total emulsion quantity. In the case of more severe tarnishing or corrosion/staining of non-ferrous metals, the application concentration should be increased. It is important to mix the bath volume thoroughly immediately after adding the non-ferrous metal inhibitor.
