- Applications
Designed for use as a heat transfer compound in both the electrical and the electronic industries, Novagard G644 is similar to the original thermal compound, G641, only formulated to a higher penetration specification (softer). Characterized by its high thermal conductivity, high dielectric constant, and high dissipation factor, Novagard G644 is an ideal material for use in thermocouple wells, power diodes, transistors, semiconductors, and ballasts, among various other applications. Novagard G644 exhibits excellent longterm storage stability, without the oil separation that is common to other brand names.
- Restrictions
Do not use in or around highly oxidative chemicals such as liquid oxygen, chlorine, or peroxides. Not recommended for surfaces that are to be painted.
