TMC 704 diffusion pump fluid is a single component, tetramethyl tetraphenyl trisiloxane, clear fluid that is chemically equivalent to Dow Corning® DC-704. Developed for use in high vacuums 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, hard carbon and crystallization.
