I hadn't heard of Licron 1755, but it sounds like it would be worth checking into. I would be most concerned about how effective it is and whether it would ever chip or wear off. Of course, the best solution is to use ESD-safe materials where possible (conductive plastics, metals, ESD laminates for bench tops, etc.), but this isn't always possible or economically feasible, and there may be existing equipment or new tools where ESD-safe materials are not available.

I did a little more web surfing and found a Tech-Spray product called Licron(r) 1755 listed as a permanent Static Dissipative Coating. Looks like a cured on coating. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Roach, David Sent: Wednesday, November 30, 2005 11:15 AM To: [log in to unmask] Subject: Re: [TN] Anti static sprays The anti-static sprays are temporary, so they have to be re-applied regularly. I am not sure how long they last, as I have limited experience with them. It would be best to check their effectiveness regularly with an electrostatic field strength meter. On a related note, in a former life, we purchased some new static-dissipative (blue) plastic totes. We sent them through an aqueous cleaner before sending them into a clean room. When we tested them, they had no static dissipative properties. The manufacturer said that the anti-static properties are removed by washing, but that the plastic would "bloom" and eventually become dissipative again. Our tests showed that this never happened. I believe they may have treated the molded plastic parts with an anti-static spray to call them dissipative, though I have no way to prove this. (This was about 8 years ago, so the properties of new products may be different.) On the other hand, conductive totes are molded with carbon in the plastic resin, so they should remain conductive over their life. The conductive totes have higher conductivity than static dissipative totes (especially after being washed :-) ).

On doing a web search I see there are many products on the market, but are these really for ESD control?. The question is, do I have to keep re-spraying the item to keep it functioning or is it a one time application? Thanks in advance.
