TMC 704 Silicone Diffusion Pump Fluids
TMC 704 diffusion pump fluid is a single component tetramethyl-tetraphenyltrisiloxane, clear fluid that is chemically equivalent to DC-7O4. Developed for deep vacuum levels of 10-6 Torr (untrapped) and 10-8 (trapped), TMC-704 performs well in tough, rugged applications with quick pump down, even after exposure to air at high temperatures. It is thermally and chemically stable, which keeps pump jets free of tars and hard carbon.
TMC 704 can be used to produce high levels of vacuum in the aerospace and electronics industries and is ideal for metallurgical and research needs. It also works well with vacuum coating operations. |

Using TMC's reclamation services,
TMC 704 can be reclaimed a number of times.
