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.

      Beat adjustment

      By dnhb · Posted

      I'd be grateful for recommendations of good sources of advice on getting clocks with balance spring - as opposed to pendulum - escapements 'in beat'.....

      Hettich Clock

      By Michael1962 · Posted

      Well I am in a bit of a quandary. I can't find the correct colour for the dial. I even wrote to Hettich a while back hoping they would give me the colour code for the dial. The reply that I received was "We don't make those anymore." I am thinking now to silver the dial and use a water transfer decal to put minute markers and the HETTICH logo (which is the very font that this forum uses) and the Made in Germany down the bottom. Not sure of the success rate of the water transfer method, but I have no other solution for the markers and logo. Handpainting is just not an option. In trying to get the top piece of the clock polished, it has progressively lost its sharp edges. My stupid hamfisted effort. I am thinking of purchasing a replacement piece of brass and drilling new holes in it for the corner posts. Why I attempted to repolish using wet & dry and not simply using a paint remover to remove the old lacquer from the brass, I don't know. You whistle and I'll point at the idiot. I also need to purchase some sheet spring steel as the two small ratchet springs that arrest the wheel that supports the weight after it is lifted by the electromagnet are worn. The two from the donor clock that I purchased are worse. I am hoping that I will be able to manufacture new springs without having to fiddle about with tempering etc to the steel. I have some ideas on that front. How many things until the clock is no longer the original? Like an axe. Heard a woodchopper on tv once saying that he had replaced the head on his axe twice and the handle three times, but it was the same axe that he began woodchopping with. 😉

      Movement holder made with 3D printer

      By Waggy · Posted

      I use the exact OD and it fits in with a little force and a pleasing 'click' so it's snug and wont rotate within the holder, but that depends on how you have set up and calibrated your printer so you may need to play with the settings/dimensions a little to allow for any discrepancies in your printer calibration. PS I just finished (2 days ago) a new revision which automatically prints the movement OD on the bottom of the holder, I'll see if I can upload it here Here is rev 4 remember to change the .pdf to .FCStd so it will open in FreeCAD - also you may need to install the LiberationSansBold font and tell FreeCAD where it lives on your PC, or change the font to something you already have on your system. Para Movement Holder V4.pdf Examples below:

      Movement holder made with 3D printer

      By Zedster · Posted

      Hi, guys I'm very interested in printing out this design as I've seen the orignals used on many occasions and I'm fed up with my movements popping out the standard Bergeon type so want to give this type a go 😀  As I've never used this type before should the movement be a snug fit in the holder? Once you've measured the diameter of the movement do you put this exact value in the spreadsheet or increase it a little 🤔 Comments would be appreciated 👍
