I bought this from Cousins which was advertised as Silicone grease. Immediately I noticed that it smelled a bit like dubbin (animal fat) and also a bit like shoe polish. The colour is also amber. 

I heated a blob of it and it immediately melted and ignited, and when I distinguished it, it continued to leave a white smoke, like a candle. 

I told Cousins that I didn't believe that it was Silicone, so they've asked the manufacturer Ho have replied saying that it is indeed silicone grease. 

Is there anything I can do to prove it otherwise? I don't care about the cost of it (£3) - it's just the principle of buying something which isn't quite what you expected. I just can't believe that this is silicone grease.

Doesn't say it's silicon grease?

It's like Bergeon KT-22? It says silicon grease but it doesn't smell like silicon? And it's not working very good either? Have used it on gaskets and it makes the gasket stick to the crowntube in no time. Use Seiko silicon grease . That's the best?

That is  a Silicon applicator for gaskets. The foam/sponge is Impregnated with the silicone. I have used these applicators for many years with no issues. The gasket/ring is laid inside & then the lid is closed and twisted a few times to apply the silicone.

Thanks. My concern is specifically if the grease is actually silicone or not. I've opened watches with dissolved gaskets before, and it's quite probable that they've been dissolved by hydrocarbon-based greases. This stuff smells hydrocarbon based to me (a bit like shoe polish).

I'll be surprised if it is not Silicone. There are different types of silicone for example I have a small tub of "Seiko" silicone which is clear and very tacky. I have also some silicone that I purchased on the cheap from ebay and is it white and does not seem as tacky but it is however silicone. I suspect this is the type of silicone that is used in these pads to allow for easier transfer.

Back to your original question I don't really see you can do anything about it anyway if Cousins are insisting it is silicone.

Interesting point you raise though about KT-22. Bergeon don't say their version is silicone, I have some from an American company that doesn't  mention silicone and it certainly doesn't look like silicone. Yet both Cousins and Walshs call it silicone (well, Walshs call it silicon for some reason). Makes me wonder if the word is being used incorrectly to mean gasket grease or something like that?

Is Bergeon KT22 definitely silicone? I've seen it advertised as silicone, but their website does not mention the word "silicone", whereas their other gasket grease does mention that it is silicone. 

Cousisnuk sell it as silicone grease. There is an other Bergeon product called silicon 7 . Interesting i will contact Bergeon and ask.

I guess this begs the question: why is something OTHER than silicone used for case back gaskets if it destroys  them? 

I've had numerous Omega F300 casebacks that I've had to soak in lighter fluid to be able to dig them out of their groove. They were mush and turned into a sticky black mess merely from age.

      Yup watchie you are entirely on my wavelength with this , you actually said what i was hinting at, what if something happens to mark ? Will someone be able to take over ? Its not that long ago that the forum was down and Mark had to step in and fix it. And you are right a wealth of information that does not exist as a whole anywhere on the planet will be lost. Can that be archived elsewhere?

      Hopefully if the issue is running costs, Mark would let us know and suggest ways of raising finance. If it's the other issue, which we are skirting around, sites can be passed onto others.   PS because I know you're all interested, I  had a bacon and mushroom sandwich for breakfast.  Hehe.

      Hi guys, the question is what is a forum, a place for discussion and passing on information, idle chat and a bit of fun and I for one are the richer for it. When in Hospital last year with the Covid being force fed oxygen and feeling total sh1t and close to the pearly gates a daily look on the forum to see what was going down helped to keep me focused on the job in hand took my mind off the problem for a short while but it was a lifeline for sure. We chat to friends for that is what they become around the world read their posts help where we can post information where we can.  I like @Neverenoughwatches some times think of members past and wonder if they are still at the watches or given up, some drop in for advise and drop out again never to be heard of again. The forum reminds me of Yorkshire hospitality, The door is always open and the kettle on the stove. Long may it continue.   My two bobs worth.
