Overview
Krytox™ XHT-BDZ Grease is the highest-viscosity lubricant within the XHT-BD series, with a base oil viscosity of 1,023 cSt at 40°C. This perfluoropolyether-based (PFPE-based) lubricant contains a nonmelting thickener that can provide superior performance at higher temperatures than conventional alternatives where thickener melting becomes a concern (up to 360°C and spikes upwards of 400°C).
Krytox™ XHT-BDZ also provides excellent wet-out on metallic surfaces due to low surface tension properties and does not interact with metal surfaces due to its chemical inertness. These properties help extend lubrication intervals and the equipment life of your system in a variety of industries, including metal processing, energy generation, and textiles.

Features & Benefits
Excellent lubrication over a broad temperature range (−5°C to 360°C)
Great wetting-out performance with low surface tension
Chemically inert and oxygen safe
High viscosity
High-temperature grease
Low oil evaporation
Nonhazardous
Thickened with a nonmelting thickener
Will shear at higher speeds
Resistance to oxidation and corrosion
Nonflammable, extended lubrication intervals and equipment life
Problems Solved
Melting grease and lubricant failure at extreme temperatures (>752°F)
Excessive bearing maintenance or replacements in high-temp applications
Highly reactive or potentially flammable greases
Poor equipment life
High stabilizer rattly
Applications
Krytox™ XHT-BDZ high-temperature grease should be used in the following:
Low-speed bearings
Pillow housings
Keyboard stabilizers
Wire stabilizer lubricants
The base oil in Krytox™ XHT-BDZ can slowly evaporate at temperatures above 360°C (680°F), and this evaporation will increase as temperatures increase. It can withstand intermittent spikes upwards of 400°C (752°F). Relubrication could be required at these temperatures to achieve optimum life.
