Alps Lubricant FOUND!

Not much to contribute but this is really interesting!

I've always been baffled by how badly most lubes work in 1st gen alps. I really regret ultrasonicing some blue sliders I have as it made them bind more. Would love to salvage them.

Any updates? A comparison with RO59 would be very interesting.

I did find almost the same product code on this pdf page 75 ... -LOCAL.pdf

It has a TB2585G -Not P but, G, and the 1 replaced with the 5. Similar though.

The thing to note is that the sheet while saying its a plastic lubricant indicates its' "x" status for use as a switch lubricant. Meaning unsuitable. Perhaps the P is different from the G though?

Regardless it is a lubricant that is to be used on plastic parts with a white appearance.

Perhaps chyros has some thoughts on this?

I still cannot help but wonder if the TB2581P is merely the currently recommended "modern" lubricant by Alps, versus the actual lubricant used in the 1980s.
I think the letters are referring to the kind of lube it is. L seems to be for Oil, S seems to be for Aerosol (Spray), G for Grease. I haven't figured out what P might mean. Keep in mind that I may be mistaken. Why don't we just ask them if they have the P version and what does that mean?

Maybe paraffin, i.e. wax.

This really is very exciting because I was about to make a post about my extensive tests these past few months, where almost daily was trying many different types of lubes and hours upon hours of polishing the sliders and housings with nail files and various sandpaper grits. Only to fail again and again. The lube used on 1st gen is completely out of this general league of lubes. And it is, unfortunately, extremely fragile.

I verified that even if you open a virgin factory lubed switch and just use a gentle paintbrush to gently dust off the rails of the housing and/or the slider, the lube will come off and the switch will lose its smoothness and have binding and stick-slip on corner presses. Just like as if you ultrasonic clean them. And I was about to make a warning post about it for not even thinking of dusting them for this reason.

We need the original spec of that Threebond lube!

Guys, as I read the spec-sheet for the 2500 series of threebond, I have a feeling that the TB2581P that ALPS recommended, was in fact the lubricant for the bottom part of the slider where the leafs are in contact with. The lubricant on the housing rails and the slider rails may be quite different.

(at least, is almost certain that whatever that lube is, it will probably be from threebond too, so we are still getting closer anyway)

What was the question that you asked them about in your email that they gave that response?

The wording they use is very specific and doesn't actually say that it is that, which I find suspicious.
In their reply to the second email, the wording is not vague at all:
The lubricant is TB2581P from Threebond.
If the question was specifically asking what was the lubricant used in SKCM/SKCL, then that phrase is unambiguous. It also seems the real deal as this type is out-of-production for decades and nowhere to be found, so it coincides with the timeframe of the production of SKCM/SKCL.

just my 2c
