The Best Dow Corning High Vacuum

Dow Corning 4 Electrical Insulating Compound can be applied by hand, specially designed automated equipment, brushing or wiping. Certain designs of grease guns may seize up with silicone compounds; test prior to use.

Dow Corning no longer offers DC-705 for sale. Midwest Tungsten has filled the gap by offering private label 705 chemically equivalent products in 250 cc bottles. Pentaphenyl trimethyl trisiloxane. MT-705 diffusion pump fluid is a colorless to light straw, single component for ultrahigh vacua in the range of 10E-9 to 10E-10 torr untrapped and 10E-11 torr trapped. The vapor pressure and backstreaming rate of MT-705 Diffusion Pump Fluid are low enough that use of traps or refrigeration may not be necessary for all ultrahigh and ultraclean vacuum applications. It has the highest phenyl content of all silicone diffusion pump fluids, and hence, the best resistance to radiation. Additionally, MT-705 has a high spontaneous ignition temperature. Replacement for and equivalent to Dow Corning DC-705. Sold as DS-705, KJLC 705, and Invoil 705 elsewhere.

Dow Corning no longer offers DC-702 for sale. Midwest Tungsten has filled the gap by offering private label 702 chemically equivalent products in 500 cc bottles. MT-702 diffusion pump fluid is a general purpose fluid designed for fast pumping of large volumes of gas. It is used to produce vacuums in the range of 10E-5 to 10E-7 torr. It is also used in vapor ejector pumps that attain vacuum of 10E-4 to 10E-5 torr. Replacement for and equivalent to Dow Corning DC-702. Sold as DS-702 and Invoil 702 elsewhere.
