Frequently Asked Questions about Vacuum GRS
Practical application and design questions — answered by SILITECH.
Bluesil Vacuum Grease: Silicone high-vacuum grease for vacuum seals, ground joints, and laboratory vacuum applications — very low vapor pressure, chemically inert. Main applications: vacuum ground joints, vacuum valves, high-vacuum systems.
Prepare the surfaces to be lubricated clean, dry, and degreased. Silicone grease is not compatible with mineral greases — carefully remove any old mineral grease beforehand. Apply with a brush, spatula, or grease gun. Important: Silicone greases must not be used for lubricating oxygen systems (explosion hazard).
Store in the unopened original container in a dry, cool place — typically standard between +5 and +30 °C, exact values see TDS. Consult the Safety Data Sheet (SDS) before use. Observe the expiration date on the packaging — Elkem guarantees the sales specifications only up to the stated date.
