Versilube G687 is from our family of general-purpose silicone greases thickened with inorganic fillers for lubrication and insulation, which are resistant to oxidation and thermal degradation. Designed for use as a dielectric compound on high voltage insulators, G687 reduces the opportunity for dirt and moisture to create arcing across the insulator. G687 prevents the formation of a conducting film of water, thereby eliminating any arc-over under wet conditions. The silicone engulfs and encapsulates any water-borne, hydrophilic particles so that the insulator remains water repellent even in dusty, highly conductive atmospheres.

G687 is also an excellent mold release and rubber lubricant. The compound may be applied by wiping, brushing, or spraying. It can also be used as an alternative to Dow Corning / DuPont Molykote HV3099.
