Teflon/PTFE getting it to impregnate hard chrome w/high nickel content
(OP)
Not my area of expertise whatsoever, but we are attempting to lubricate a chrome shaft that has a rubber seal running up and down it. We've tried both moly disulfide and tungsten disulfide and the seal just wipes it off after only a few passes. Teflon looks like it is going to be the next thing we try but we are having trouble getting it to stick to the chrome. This all needs to be able to be done at room temperatures without removal of the shaft itself. What binder or carrier could be used to help the telfon or PTFE to actually stick to teh chrome? There is oil that sits behind the seal and we can't have the lubricant mix with the oil so it really needs to be non-oil soluble. Any help would be appreciated. Thanks.

I've always wanted the opposite to happen.
The are rubber and fluorocarbon wiper seal with added lubricants

Your teflon wouldn't last very long even if you could get it to stick. If the seal is that tight, it will abrade the teflon off or the pressure alone would cause the teflon to flow.

As well known the rub, literally, comes in selecting the right physical configuration and material compatibility
You might want to look over the products from the following company.

If you could clear up the problem you have it would help. There many parameters to consider in sealing a rod or shaft so a little more information like surface finish, speed, diameter, etc would help.
