Dielectric Coatings

A dielectric coating is a nonconductive, i.e. an insulating, coating. 

At Jaro Corp, we manufacture and apply our own dielectric coating: JARO 650 Series Polyimide.  This coating is a proprietary polyimide thermo set material, offering outstanding characteristics which include: 

• Remarkable resistance to high temperatures.  It also performs well at cryogenic levels.


• High resistance to oxidative degradation, weathering and radiation.


• Excellent resistance to abrasive and frictional wear.


• Unaffected by solvents or oils.


• Provides insulation against electricity, (up to 3100 volts per mil.)


• The surface finish is glossy and red in color.


• It is applied in a thin film, which is important where space is of prime consideration.  JARO 650 Series builds up at approximately .00025” per application.


• Custom formulations are available.
