FAQS: Etching Chemicals
The electrolyte is basically salt-water solution and the neutralizer is basically a water soluble cutting oil.
Yes, we can provide certificates of compliance. The cost is $25.00 and must be part of your purchase order.
The shelf life of the electrolytes and neutralizers are one year from date of manufacture.
Yes, SDS's are included with every shipment.
We have two electrolytes that can generally mark almost any ferrous or non-ferrous metal: MSC 1 and MSC 4. We also have over 120 electrolytes that we can recommend and custom blend for your application. Please send us your part for a test mark so we can customize your solution.
Monode has a full graphic arts department that produces stencils. Customers may send a high resolution black & white electronic file to reduce the set-up cost. For fabric stencils black & white artwork with a minimum line weight of .005" is needed to work within the weave of the fabric. Too small or too thin will not work as it falls within the apertures of the weave.
Fabric: There are several types of fabric stencils depending on your application for intricate small patterns to deep etching. Fabric stencils can mark from one to potentially infinite impressions depending on your use. Have your Monode sales professional help you choose the right material.
Paper: Paper is available in three standard sizes and many different lengths (custom sizes available by quote) for deep and shallow applications to fit the technology printing the stencil. Paper stencils are generally used for small batches of impressions. They are often used for serial number applications and 2D data matrix bar codes, limited by the resolution and capability of the generating technology.
As a general rule for both types, for best results make sure the stencil is properly cared for, rinsed out, and stored correctly, and that the marking is done using the correct settings and in optimum conditions.
Rust is generally created by a process step not being correctly followed. As electrochemical etching is a salt water based procedure, failure to properly remove (neutralize) the etching solution (electrolyte) can cause a surface rusting issue. Please refer to our neutralizing procedure (PDF) or contact our service team regarding your specific issue.
