VGE-7031
IMI-7031 Varnish (formerly GE 7031 Varnish) (1 pint can) . IMI-7031 Insulating Varnish and
Adhesive possesses electrical and bonding properties which, when combined with its chemical
resistance and good saturating properties, make it an excellent material for cryogenic temperatures.
As an adhesive, IMI-7031 bonds a variety of materials, has fast tack time, and may be air dried or
baked. It is also an electrically insulating adhesive at cryogenic temperatures and is often used as a
calorimeter cement. When soaked into cigarette paper, it makes a good, high thermal conductivity,
low electrical conductivity heat sinking layer. Maximum operating temperature: 423 K (150 °C).
