ADDOTHERM K-SAT is a synthetic base, High performance, very high thermal stable Heat Transfer Fluid, designed for the use in non-pressurized systems up to 350 °C (662°F) with maximum film Temperature of 375°C (710°F).

ADDOTHERM K-SAT has as good low temperature properties, reducing the need for heat tracing, has a high flash point, has excellent thermal stability at the maximum use temperature, Degrades primarily to low molecular weight products—no build-up of high molecular weight products that must be removed from the system. • Has a single dose oral toxicity that is considered to be extremely low.
