TMC 705 silicone diffusion pump fluid is a single component, pentaphenyl trimethyl trisiloxane, clear fluid developed for use in ultra-high vacuum levels of 10-9 torr (untrapped) and 10-11 torr (trapped). TMC 705 is superior to Dow Corning® DC-705 and other diffusion pump fluids that are blends, often containing significant amounts of materials originating from China.

Product Datasheet


TMC-705 performs well in high purity metalizing applications where quick pump-down is needed, as well as thermal, radiation and chemical stability.

Because of its low vapor pressure, TMC-705 can reduce the chances for contamination in untrapped systems by a factor of 100 or more compared to TMC-704 and other fluids. The vapor pressure is so low, that deepest vacuum levels can be obtained with water cooled baffles alone.

Using TMC Industries' reclamation service, TMC 705 can be reclaimed many times, saving you money and disposal cost.
