XL0775

100% SYNTHETIC HIGH TEMPERATURE PAO GREASE WITH GRAPHITE

XL0775 is a 100% synthetic graphite-based grease engineered to perform in critical high-temperature applications including ovens, kilns, slide ways etc.

XL0775 features exceptionally low volatility due to the high molecular-weight olefin polymer base stock. As the ambient temperature increases, this olefin will evaporate slowly leaving a layer of pure highly refined graphite residue on the metallic surfaces thus preventing metal-to-metal contact.

XL0775 can be used in constant temperatures of 400ºC / 750ºF at which time the base stock will volatilize at an accelerated rate. The graphite residue will withstand temperatures of more than 1200ºC / 2200ºF with negligible degradation.

XL0775 is highly thixotropic and is an excellent grease for high load and low rpm bearings. Precautions must be taken not to over-lubricate bearings, and regular inspections must be performed to determine re-lubrication cycles.

XL0775 is formulated with high polymer base stocks, which result in exceptionally low volatility at higher temperatures, as depicted in the chart below:
