Novagard G687 is a grease-like material formulated with select polydimethyl siloxane fluids in combination with inert, amorphous silica fillers and is designed for use as a dielectric compound on high voltage insulators.
Novagard G687 prevents the formation of a conducting film of water thereby eliminating any arcover 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. Novagard G687 is also an excellent mold release and rubber lubricant. The compound may be applied by wiping, brushing, or by spraying.
