Re: Replacement for methyl ethyl ketone

Hi Tammy,

I am not familiar with SAGE, but in the interim have you tried stoddard solvent or naphtha? That's what litho printers use for blanket washes. It's high VOC but has a low vapor pressure (<2 mmHg) and is not a carcinogen. I am sure that there are water-based cleaners available that will work as well too but you will need to do some parts testing.

Good luck,

Any suggestions on a replacement for methyl ethyl ketone in cleaning operations?  A company that screen prints with  solvent inks uses MEK to clean the equipment in a cold immersion tank or by hand depending on the size of the part to be cleaned.  They are desiring minimal change to the process, but a substitute for MEK.  I tried SAGE, but unfortunately, the high ranked items on the reults list will not work to remove his solvent inks (e.g. surfactants).  the materials that need cleaning are predominantly stainless steel.  The facility also would like to avoid carcinogens.
