Title: Graphite Lubricant?
Post by: reaxas on Mon, 11 May 2015, 08:55:15
I've recently picked up some lube for my ErgoClears and I was wondering what everyone thinks about using Graphite Lube on switches? On paper it seems like a pretty good alternative to the regular ones.

Graphite is electrically conductive. I cannot see this property making for a good lubricant in an electrical switch.

It's also messy as ****. Everytime I lube my bicycle lock with it I can practically write off my jeans and t-shirt.

Oh damn! I guess I won't be using that then! I was wondering if there were any easy to find alternatives? I've looked around almost everywhere is Mississauga, Ontario, and I can't seem find Teflon Silicon Lubricant. :( Ideally it'd be local, but if there's a fast delivery time online, that'd work too!

Be patient and order the Krytox.

A spoonful of it will last for months/years and do a dozen keyboards.

nubbinator has a lube comparison (https://geekhack.org/index.php?topic=71442.0) coming up.

Still waiting on the stuff to actually ship to me.  I should be getting the Molybdenum disulfide soon.  I went with that as a dry lube for the testing since it's supposed to have good lubrication properties, likes plastic and doesn't necessarily need to be in suspension, and it's non-conductive (or at least not enough to cause any problems).

I should also be getting some Teflon dry lube from CPTBadAss.

Last time I checked, Zeal had Krytox in stock. EK also has Mechlube2.

Yeah graphite lubes would be bad in this situation for the reasons provided.  In the olden days of CPU overclocking, certain chips would need traces drawn on the chip with a pencil.  It can conduct that well.

Fair warning, that molybdenum is a 50 state carcinogen, not just in California.  Just wear latex gloves and wash them after and you will be fine.  I am not sure what level of exposure increases risk by a statisticaly significant amount, but our supervisors in the Navy were anal about that.  We had a couple parts that were coated with it as a permanent coating and had to be cleaned and greased every flight.

Molybdenum Disulfide is pretty harmless.  It's not rated as a carcinogen and there haven't been any damning studies of it.  The National Library of Medicine at the National Institute of Health lists it as practically non-toxic.  And that's a quote: (http://toxnet.nlm.nih.gov/cgi-bin/sis/search/a?dbs+hsdb:@term+@DOCNO+1660)

You are right.   That was a total brain fart on my part.  The grease we used was molybdenum based.  The parts were copper berilium coated.
