So we started using the stainless steel containers for mixing our discharge. Just trying to cut down on needless waste of plastic mixing containers.
If you do several mixes of discharge a day times 5 days a week times 52 weeks a year that is a lot of waste of plastic. But with testing we have not noticed any problems with any job so far. And leaving the ink in the container we have not had any corrosive issues. But then again I should probably consult a chemist in reality. Just throwing out some info for anyone else interested.
