Thank you all for commenting.
Well tell you that this mek, is a methyl ketone whose solution is almost 50%, (domino cleaner) is the product used in inkjet lotifiers, for head cleaning, although it is suitable according to What places (food industry for example), I always work with him with the extractors running, I only in the room and with the mask on!, already in case I wear the built-in glasses!
that TET, butyl acetate-acetone I have it too, is another lotifier cleaner like mek. (image cleaner).
and if it is very good of cement glue.
the smell is very unpleasant and the effects that it has according to plastics are unpleasant, but something that it has when putting plastic is that the damage is reduced on the plastic of the plane.
