Due to the use of primary amines there is no risk of formation of nitrosamines according to the current
state of knowledge.
Furthermore, Zubora 35 H Ultra 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. When exceeding the limit value for nitrite according to TRGS 611 a partial or complete change
of the emulsion is not necessary.

Due to selected highly effective EP additives Zubora 35 H Ultra is suitable for cutting processes
of most difficult demand. The product can be used for machining steel, cast iron and aluminium.
Moreover, Zubora 35 H Ultra is suitable for machining sensitive aluminium alloys as AL 2024
and AL 7075. Due to a special formulation Zubora 35 H Ultra is particularly long-term stable.
The EP-additives effect a longer tool life and enable the working with high cutting speeds.
Thus, a high process security can be guaranteed even for very difficult working operations.
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 (210 - 430 ppm CaCO3).
