SilOil M20.195/235.20 can be used in the range from -20°C to 195°C (for
open systems) and to 235°C in externally sealed systems (Unistats). It
should be borne in mind that, at high temperatures, SilOil
M20.195/235.20 can be chemically altered by oxidizing media, such as
air, or substances with a catalytic effect, such as acids, lyes and various
metal compounds. An increase in viscosity, and possibly even gelling of
the fluid owing to crosslinking reactions, must be expected in the presence of oxidizing agents, while contact with products having a catalytic effect usually induces a process of depolymerization, resulting in a
drop in viscosity.
