Methyl Ethyl Ketone (MEK) is used widely as cleaning agent, I am given an assignment to label all the plastic/ nylon scraper that is used in the production to prevent cross contamination from happening. However I am unsure of what kind of material that resist MEK/ Acetone and can last long. Can any senior engineer give me some advice on it? Or any other effective labeling method that is better than the current one?

Hi karboon,

 

I think you'll need to web search for a "compatability chart" for solvents and plastics or other "materials of construction".

 

Then perhaps for those made of susceptible materials, perhaps a colour coding method of identification could be used. Paint them a certain obvious colour, or replace them with a more suitable material.
