Electrolytes from Ostling Etchmark……..

From Aluminum to Zinc – we have suitable electrolytes for each material.

Which electrolyte?

One of our strengths is our large electrolyte range which can be used on almost any electrically conductive material. Many of our electrolytes can be used on different materials. The selection of the correct electrolyte is very important to obtain the best results.

We can advise you on the best electrolyte for your marking needs in a matter of seconds. It may be necessary for us to run tests on samples of your material prior to final recommendation and we can also supply a detailed report included suggested machine settings.

This service is provided completely free of charge!
