HV Insulator Silicone Grease M496 1000g (Transparent to White)
Single component modified silicone system does not harden or dry, or melt after 1000 hours at 200 Celsius temperature conditions.
Features and Usages

  • Excellent work stability
  • Non petroleum based, specially for rubber/NPRM/Plastics/neoprene/ABS/PU/non-conductive parts
  • Non Melting even in hot climates
  • Excellent water repellent
  • Good di-electric and lubricating properties.
  • 662/M496 readily wets and adheres to dry surface of metals, ceramics, rubbers, plastics and all insulating materials, giving them very high surface resistivity even under moisture condensing conditions.

About Silicone Grease on Electrical


Silicone polymers have very good electrically insulating properties enabling silicone grease to be used as an electrical insulator and lubricant. On the micro level they can be used to lubricate switches, electrical contacts and cable joints.


On a much larger scale they have been used for many years on high voltage insulators to provide environmental protection and prevent arcing or corona discharge.  The addition of a pink dye has enabled inspection to take place from a distance to see if the grease has remained in place.
