DESCRIPTION
Dow Corning® High-Vacuum Grease is
a stiff, nonmelting 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
Customer Service at 1-800-248-2481.
