MT-704 Diffusion Pump Fluid - 1 Gallon
Description
Description
Replacement for and equivalent to Dow Corning DC-704.
Tetramethyl tetraphenyl trisiloxane. MT-704 diffusion pump fluid is a single component fluid for high vacuums of 10E-6 to 10E-8 torr, untrapped or 10E-10 to 10E-11, trapped. It performs well in tough, rugged applications and offers quick pumpdown, even after exposure to air at operating temperatures, although this is not recommended.
Appropriate for use in medium and large pumping speed diffusion pumps
Lower attainable pressure
Offers higher resistance to hydrolysis and oxidation
For diffusion bonding, vacuum metal casting, and other uses
Sold as DS-704, KJLC 704,and Invoil 704 elsewhere.

Is MT-704 a direct replacement for Dow Corning DC-704?
Is MT-704 a direct replacement for Dow Corning DC-704?
Yes. MT-704 is equivalent to and a replacement for DC-704 — the same tetramethyl tetraphenyl trisiloxane chemistry sold elsewhere as DS-704, KJLC 704, and Invoil 704.
What vacuum level can it reach?
What vacuum level can it reach?
As a single-component fluid it supports high vacuums of 10E-6 to 10E-8 torr untrapped, or 10E-10 to 10E-11 torr with a trap.
What applications is it suited for?
What applications is it suited for?
It performs well in tough, rugged applications such as diffusion bonding and vacuum metal casting, and is appropriate for medium and large pumping-speed diffusion pumps.
What happens if the fluid is exposed to air?
What happens if the fluid is exposed to air?
MT-704 offers quick pumpdown even after exposure to air at operating temperatures, although operating that way is not recommended. It also offers higher resistance to hydrolysis and oxidation.
