DESCRIPTION
Dow Corning® High-Vacuum Grease is a stiff, non melting silicone lubricating material that maintains its consistency from -40 to 204°C (-40 to 400°F). It is used in applications similar to those for Dow Corning® Stopcock Grease,
and is the recommended replacement for that product.
Dow Corning High-Vacuum Grease is recommended for vacuums reaching between 1 x 10-5 and 1 x 10-6 mm Hg. It is recommended that the grease be preconditioned under vacuum and temperature until these limits are reached. For details on attaining higher vacuums, please contact Dow Corning
