Main Applications:
- Extensively used as semiconductor transistor*s stuffer; electric
insulation for instrument; lubricant at low and high temperature; foul-borne arc
resistance for high-voltage insulator.
- Can protect electric junction from corrosion and rust, and protect
electric instrument and apparatus from shock. Also can be used as damping medium.
- As release agent and defoamer.
Notes:
- Keep away from fire, sunlight and rain. Keep good ventilation
during storage.The effective store time is a year. Beyond the time, it still can be used
after being tested and qualified.
- Transported as non-hazardous chemicals.
