Anti-seize grease

danfoto · Post by **danfoto** » 31 Mar 2021, 7:24pm

My tube of Copaslip grease has now finally expired, and it occurs to me to replace it with the white equivalent that seems to be always used nowadays to prevent seizing of ally seatposts in steel frames and suchlike.

Can anyone please recommend a readily-available brand of just such a grease?

I've used Coppaslip since I was an apprentice 40 years ago. It would never occur to me to use anything else as an anti-seize grease.

So have I, onlyin my case that was 50 years ago. But I don't want Copaslip now. I want the white stuff

Loads of really detailed threads on grease/ anti seize already - Brucey started an outstanding one previously.

I’ve used Shimano LokNot for about 20 years on bikes. Think they now just call it anti seize grease. I bought it because I believed Coppaslip was designed for steel against steel and was unsure whether using copper between alloy and steel was wise. I’ve no idea if that is true or an issue, but the Shimano stuff certainly works well. Quite expensive but lasts decades. And it is white.

the 'white stuff' is just lithium grease, Weldtite, Morgan Blue, Park - well pretty much everyone offers it in varying quantities and prices.

I've been using Shimano Anti Seize for the last 15 years or so.

Never had anything seize while using it.... maybe it's doing its job .... or maybe nothing would have seized anyway!

Grease is grease.
The best thing to do, is to not forget to remove stuff and put more grease on the threads.

Copper grease is good for "almost fit and forget" but as I said, the best thing is not to forget to remove stuff and put more grease on the threads. More often, the better.

That's fair enough, but around where I live one winter's commuting is enough to begin to seize bottom bracket cups. ...Or it was before I used anti seize :lol:

I discovered this because my Campag Chorus bottom bracket bearings would just about last a winter, and on a couple of occasions I had to cut the cups out to remove the BB. That is about the time I started to experiment with different lubrication methods and Token BBs, since when I have had no seizures.

White anti seize is usually either aluminium or ceramic based.

I just use waxoyl on my seatpins - rarely ride in the rain and have mudguards anyway, which makes a difference.

Is it just lithium grease? White lithium grease is white. White anti seize is white. Toothpaste is white too. Are they all the same?

In fact, Shimano anti seize paste doesn't use a lithium soap but an aluminium one. (It shares some ingredients with toothpaste btw.)

Many anti seizes have grease bases (ie oil plus soap) but in contrast to lubricating greases they will typically have much pronounced higher solid contents, e.g. fine copper in copaslip or other metallic compounds, molybdenum disulfide, various other stuff that will have the aim of preventing seizing and galling. Regular grease is ok in a pinch, anti seize is better if you've got it.

I have been experimenting with 'red rubber grease' for several years now - for instance when I have had the pedals off, red rubber one side, copper slip the other. And so far red rubber has performed as well.

We use fluorinated grease frequently at work (primarily as it is oxygen safe) and it’s non-reactive nature interested me.

I used it on my commuter and, over a winter, it seemed to outperform the grease I had been using till then.

Well chaps this is all very interesting but not exactly helpful. As I said in my OP ...
