conveyor chains that are subjected to moist conditions
or frequent temperature cycling that could allow
condensation and rusting to occur.

Krytox™ GPL 294–297 and Krytox™ XHT-EP298–299
have been formulated for high-temperature applications
that need both high load carrying capacity and anticorrosion protection. Typical applications include

Note: Krytox™ GPL 295 has also been called TLF 8923. Krytox™ GPL 297 has been tested as TLF 8945.

In testing, the Krytox™ 29X series shows improvement in load carrying and wear prevention over standard Krytox™ greases.

The score load is the minimum load added to the system at which scoring or seizure occurs.

2The scar width is the average scar width at the load corresponding to the OK load value.

Performance Lubricants

Krytox™ GPL 577 is formulated with a high-viscosity baseoil and special additives. This results in a grease that canwithstand extreme conditions of temperature and load.

grease that evaporates very slowly under conditions ofhigh vacuum or temperature. Like all standard Krytox™
products, Krytox™ GPL 577 is nonflammable andcompatible with oxygen, and will not react with mostchemicals. Consult our “Krytox™ Oil and Grease General
Overview” for more information.

The high viscosity of the base oil combined with theadditives yields a product that is able to maintain agood lubricating film in very slow speed or high load
applications. The high base oil viscosity also results in aProduct Properties of Krytox™ GPL 577 Grease
