G641 can be used as a direct alternative to Dow Corning / DuPont Molykote DC340.

As a non-curing material, Versilube G641 offers excellent heat transfer in large and small electrical and electronic components. Characterized by its high thermal conductivity, high dielectric constant, and high dissipation factor, G641 is an ideal material for use in thermocouple wells, power diodes, transistors, semiconductors, and ballasts.

  • Temperature range: -40°C to 205°C
  • TC=0.7 W/mK

G641, or G644 – a softer, lower viscosity version of G641 – can be used as direct alternatives to Dow Corning / DuPont Molykote DC340.
