Due to the use of primary amines there is no risk of formation of nitrosamines according to the current state
Furthermore, Zubora 67 H Plus is inhibited against the formation of nitrosamines, i.e. that even if there are any secondary amines and nitrites (e. g. through foreign carry-over) no stable N-nitrosamines can be formed. Therefore, when exceeding the limit value for nitrite according to TRGS 611 a partial or complete change of the emulsion is not necessary.

Zubora 67 H Plus can be used for cutting operations up to medium difficulty. Furthermore, it is well suited
for grinding. The product can be used for machining steel, cast iron and aluminium.
Due to a special formulation Zubora 67 H Plus is particularly long-term stable. The innovative additive package effects a longer tool life and enables the working with high cutting speeds. In addition, Zubora 67 H Plus is ideally suited for cutting operations with small diameter. This advantage guarantees high flexibility for different cutting processes mainly in central systems and working centres.
The necessary working concentration depends on the difficulty of the operation and the material.
Recommended hardness of the preparation water:
12 to 24°dH.
Grinding 4 - 5 %
Metal cutting 5 - 7 %
