[lawrenceloklok]

Can I use the following grease to seal my eyedropper pen? Although the purpose of this grease is for electronic devices use.

I am not familiar with this product. It does not specify 100% silicon. Any number of chemicals, including petroleum derivatives, are reactive with plastics. In such cases, the "seal" is temporary.

Eyedropper nightmare !

I know there is a risk, so I am seeking advise. But I have no choice, it is difficult to find silicone grease in Hong Kong! And the cost of online shop is high, it is not worth buying 5 dollars stuff with 20dollars transportation cost.:-( Edited June 27, 2017 by lawrenceloklok

Nope! Go Mongkok around Nathan Rd there's lots of Radio Control model shops.

 

Buy some silicone grease for RC car differential, try 50,000 or 100,000wt if you want really sticky stiff grease for use in sealing threads.

 

I use something lighter eg 7,000wt for lubricating moving parts like a piston & screwthread.

 

For o-rings I prime them with silicon oil, also used in RC shock absorbers

You will want to buy the Silicone Grease which can use with the o-rings and 100% pure Silicone

 

If you try to search Silicone Grease for Scuba Diving will be the one you need

The transportation of silicone grease from China to Hong Kong is strictly forbidden.

You need to check the link provided above. If it's anything but 100% silicone, then no.

The link is for what?

 

 

Not often that you find a post that manages to be abrupt and rude all within 5 words.

 

The link gave you an address in Lockhart Road of a company that sells silicone grease that is suitable as a seal for an eyedropper pen.

 

You're welcome.

...it is difficult to find silicone grease in Hong Kong!

I'd look at the hardware store, somewhere that sells plumbing supplies.

Only buy something that says 100% silicone. If it says it's mold resistant, do not buy it.

 

Also, you can go on Facebook and pose the question to this group, they are very knowledgeable, friendly, and extremely helpful:

Try a store that sells skin-diving supplies, that's were I bought mine.

Hi, I haven't bought servisol in a while, but it was a white dielectric grease. Not bad for heatsinks, but very different properties from the silicon grease you want.

[Ron Z]

Servisol silicone grease MSDS.

 

When in doubt, a Google search will usually turn up a technical data sheet, an MSDS or both, which will tell you what is in the stuff. This appears to be silicone grease, not heat sink compound.

[Flounder]

Ah, my mistake - I think this must have been the one I had.

Edited July 29, 2017 by Flounder

[Ron Z]

..but I agree with you, silicone heat sink compound wouldn't be good. My comment about checking for an MSDS wasn't directed to you so much as to say to those who were asking that the answer is easy to find in most cases. I end up doing a Google search half the time myself.

Thanks Ron, I've bought items from this Company before so I know their prices are keen and they provide a good service.
