Posted By Paul Leadbetter Peter Is MEK used for its chemical properties or for its physical properties? If it is being used for its chemical properties then there may be little choice as any change will affect the reactions involved. If it is being used for its physical properties, such as boiling point or its ability to dissolve other substances, then you should be able to find an alternative. I would have thought that your supplier would be able to help in choosing a suitable substitute. Regards Paul Leadbetter

Posted By Peter Rees Paul, Roger, The reason that we are currently using MEK is to remove an ink code on packaging that shows information such as use by date, date manufactured etc. As I/we work in the food industry this information is important to be correct, and so if the wrong info is 'stamped' by the machines then, instead of wasting the packaging, the coding is wiped off and the packaging reused. Although I have only been at this site for a while, I am assured that alternatives were looked at (this would be over 12 months ago, though). I cannot comment on which alternatives, or what results were obtained. Thanks for any help.
