Fomblin® UT18


Product Overview

Fomblin® UT18 (now known as Klübertemp GR UT 18)  is a homogenous white grease suitable for lubricating mechanical parts used in wide temperature intervals ( from – 30˚C to 150˚C with peak temperatures up to 200˚C ).

Fomblin® UT18 Grease is particularly suitable for lubricating friction mechanical parts subjected to medium loads, where standard mineral and synthetic lubricants are not resistant to temperature and air degradation.


A few of the critical uses of Fomblin® greases include:

Oxygen and chlorine valves and pumping systems,

Nuclear industry lubricants

Instrument lubricants, Lifetime sealed, maintenance free bearings.

Lubricants for gasoline tank floats.

Bearings exposed to high temperatures, moisture and aggressive chemicals.

Fomblin® UT18 is used in lubricating special optical and micromechanical equipment.
