MIF Developers

! IMPORTANT NOTE REGARDING AZ 826 MIF DEVELOPER !

Recently we were informed by the manufacturer Merck, whose distributor we are, about changes of the product AZ 826 MIF Developer.

STEP 1: We had already informed you of the first change at the beginning of 2019 with the letters "AZ 800 MIF Developers PCN Letter". This change affected a surfactant (which is an additive), of which the production has been stopped by a raw material supplier.
Fortunately, Merck was able to obtain the exact same substance from another raw material supplier, so that this change did not have a negative impact on any of our customers' tests "AZ 800 MIF Developer techn. Daten".

Now we would like to inform you that this change has been implemented since January, so that the "old" material will only be sold and then the transition to the new material will take place.
If you are interested in a sample, please feel free to contact us.

STEP 2: The European Union has listed a substance in Annex XIV REACH that may no longer be used from January 2021. The AZ 826 MIF Developer contains this substance as an additive. A task force at Merck has worked on an alternative and has now found a comparable additive and presented a process-technically equivalent successor for the AZ 826 MIF Developer: the AZ 2026 MIF Developer. We have also provided you the official product change notification "AZ 826 MIF Developer PCN Letter" together with a comparative study of the AZ 826 MIF with the AZ 2026 MIF "AZ AZ 2026 MIF vs. AZ 826 MIF".

From March 2020, samples of the new AZ 2026 MIF will be available, which we can then provide in sufficient quantities for your tests.
Please let us know how much you will need for your tests and any qualifications so that we can arrange the material for you accordingly. Of course, we assure you of our full support for any problems with the changeover, but we assume that in most applications this change will go unnoticed.

Thank you for understanding!

We will gladly send you samples on request.
