Dow Corning vs Dielectric Grease

[Golias]

What is the diference between the two?

Umm, AFAIK Dow Corning is a brand name, rather then a product name....

never heard of the first.

dielectric grease can be made of many things, if you cant find it just use vaseline :D

Vaseline will work, but isn't the best choice as it is water based, and also liquifies when heated.

If you refer to Dow Corning -Conformal coating- is a cover that hardens -like candy- when is dry.

Is very useful to use instead neoprene gaskets for insulation. However to remove it, you need Xylene.

Dielectric grease is more easy to use and removal - isopropyl alcohol-, prevents corrosion, but can corroded, doesn't become hardened. Is better use Dielectric grease with neoprene gaskets.

no, vaseline is based on mineral oil and does not contain any water.

but yes it gets liquid when heated. it starts to melt at around 40-50°C.

Actually at least some is water based, as I have some here..

vaseline is a brand for a mix of parrafine oils. to be able to call something vaseline it has to be water free and contain a certain mix of parafine oils.

parrafine oils are not reacting with almost anything, BUT they do react with some silicon based gum and seal strings and can eventually damage them and make them loose.

so if you have access to dielectric grease always go for it over vaseline!

most dielectric grease is based on silicon oils and will therefore, naturally :D, not have any effect on silicon based gum or seal strings.

some dielectric grease contains carbon though, and this might lead to corrosion on alumiun parts it has contact with... but i doubt anybody will use something made out of aluminium in his rig, unless it is a part for a waterblock, but those are usually hard anodized and it shouldnt be a problem

The box, says Dow Corning Electric Grease. I can't remember the model.

conformal coating is not used as an insulation it is used to protect your board if it is exposed to moisture, in other words it water proofs your coated parts it in no way insulates...
