Coating Glass with Fluorocarbon Coating

Question:

I am a manufacturing engineer in charge of the paint line. We manufacture analytical instruments. We decided to coat one surface of a glass component with a self-lubricating, non-stick coating. I’m interested in trying to find a fluorocarbon coating that I can apply onto a glass surface that will be stable afterwards and that won’t leave solvent/grease residues on other surfaces that come into contact with the coated surface. I came across a web posting about fluorocarbon dispersions (in either water or a solvent). If you can help us in this project, that’d be great. J. J.

Answer:

Although my company coated numerous parts and products with these non-stick coatings, none of them were glass surfaces. Therefore, I would be of limited help to you. But I do know that films formed from either an aqueous or solvent-containing dispersion will be stable after processing. That is, they will not leave solvent/grease residues on other surfaces contacting them. I suggest you go back to the original web site for help in getting the supplier’s recommendations for coating glass surfaces. Tell them what you want to do, and give them an exact description of the substrate. I am sure they will be glad to help you.
