KJLC Silicone Pump Fluids
Features:
- Use in identical applications requiring Dow Corning DC 704®
- Useful in medium and large pumping speed diffusion pumps in a wide variety of research and production applications
- High resistance to oxidation and hydrolysis at operating temperature
- Ideal fluid for aggressive applications requiring ultimate pressures (without trapping) in the 10-7 Torr range
- With first class LN2 traps, chamber pressures can approach 10-11 Torr range
- Applications include vacuum metal casting, diffusion bonding, and instruments (electron microscopes, TOF mass spectrometers, etc.)
- 704-T offers a higher resistance to crystallization
NOTE: Do not use silicone fluids in mechanical pumps.
Features:
- Use in identical applications to Dow Corning DC 705
® fluid - Low vapor pressure and low backstreaming rate make LN2 traps unnecessary for pressures in the 10-8 Torr range
- With first class LN2 traps, the ultimate pressure can reach 10-11 Torr
- The high stability and high spontaneous ignition temperatures of this top-of-the-line diffusion pump fluid make it ideal for use in space-simulation chambers
- Applications include thin film coating systems, inexpensive surface science systems, and plasma physics research
NOTE: Do not use silicone fluids in mechanical pumps.
Crystallization / Solidification
Known sensitive applications where 704-T may provide a better solution with a higher resistance to crystallization:
- Optical coaters (lens) with high throughput system
- Oxide deposition applications
- Glass coaters
- Air leaks are present
