According to current knowledge, there is no risk of nitrosamine formation through the use of primary amines.
In addition, Zubora 67 H Ultra is inhibited against nitrosamine formation, i.e. no stable N-nitrosamines can be formed in the presence of secondary amines and nitrite, e.g. from external entrainment. If the limit value for nitrite according to TRGS 611 is exceeded, a partial or complete replacement of the working emulsion is therefore not necessary.
