Dow Corning® High Vacuum Grease is a stiff, non-melting silicone lubricating material which has temperature range of -40ºC to 200ºC. Although it has a good stability at the high ambient temperature range than most hydrocarbon greases, it shows a higher outgassing rate at room temperature.
It can be used for high vacuum systems up to the 1x10-6 mbar (1x10-6torr) range.
Due to it's initial outgassing, it is recommended to condition vacuum system before use.
Not for use in electron microscopes. Also not recommended for use in evaporators which need to be Si free.
Shelf life is 60 months from date of manufacture for unopened containers and stored at normal warehouse conditions.
