Substitute for MEK in Gunwash?




Hi
We use gunwash that contains MEK for our electroformed masks to wash off any 2 pk & 1 pk paint, etc, which it works well. Is there an alternative that we can use to clean the masks that is less toxic with no MEK but rips off the paint as easy?
Many thanks,

MEK / methyl ethyl ketone is generally considered to have low toxicity and is well understood. Beware of substituting the 'new' wonder solvents which have not been fully investigated.

The main problem with MEK is flammability but it is much better than acetone which is closely related.

Why do you believe that you have a problem. Gunwash should not come into contact with the operator.

If you really must find a substitute, it will depend on the maskant so ask the supplier.

Please be careful when looking up toxicity data The MEK you want is methyl ethyl ketone not MEK(mitogen-activated protein kinase)!

Test with mineral spirit (odorless)in a spray booth or by immersion; and follow safety precautions.
