Specialty Fluids MT-704

DESCRIPTION

Specialty Fluids MT-702, MT-704, and MT-705 Diffusion Pump Fluids are designed for fast pumping of large volumes of gas or vapor in production operations.

MT-702 Diffusion Pump Fluid is a general purpose fluid created for rapid pumping of large quantities of gas. It has an identical chemical formulation to Dow Corning, DC-702. It is: Mixed phenylmethyldimethyl cyclosiloxane. It is designed to produce vacuums in the range of 10-5 to 10-7 torr. It is also effective in vapor ejector pumps that attain vacuums of 10-4 to 10-5 torr.

MT-704 Diffusion Pump Fluid is a single component fluid designed for high vacuums of 10-6 to 10-8 torr (untrapped) and 10-10 to 10-11 torr (trapped). It has an identical chemical formulation to Dow Corning, DC-704. It is: Tetramethyltetraphenyltrisiloxane. It performs well in difficult applications and offers quick pumpdown, even after there has been exposure to air at operating temperatures.

MT-705 Diffusion Pump Fluid is a colorless to straw colored, single component fluid designed for ultrahigh vacuum applications in the range of 10-9 to 10-10 torr (untrapped) and 10-11 torr (trapped). It has an identical chemical formulation to Dow Corning, DC-705. It is: Penta phenyltrimethyltrisiloxane. The vapor pressure and backstreaming rate of MT- 705 Diffusion Pump Fluid is so low that use of traps or refrigeration is not required for some ultrahigh and ultraclean vacuum applications.
