We make LPISM and screen inks by the tonne around the world. In our resist manufacturing plants we always use a green two pack epoxy floor paint. Generally, provided you clean up before resists get really hard, these floor paints last years without breaking up.

We are expanding our facility and part of the expansion includes the screening department. When we built the facility 8 years ago we used vinyl tiles on the floor though out the building. This made it easy to keep clean and gave it an overall professional look. The problem in screening is that whenever soldermask or legend material is dropped on the floor and a solvent coated rag is used to wipe it up it takes part of the surface with it. The appearance has become so gross that we try to avoid the area as much as possible when giving customer tours. Please,don't suggest getting neater screening personel. I am fond of the ones we currently have. Is there a coating that could be applied that is strong enough to withstand the solvent (acetone) used for cleanup and still look good and hopefully provide a non-slip surface. The only option I am aware of is epoxie paint, but I have used it in other applications and been somewhat unhappy with the results. Any suggestions?
