DESCRIPTION
Hybase® GFX500 is a 500 TBN oil soluble overbased calcium sulfonate. Hybase® GFX500 is designed to produce a high quality H-1 incidental food contact overbased calcium sulfonate grease. It is made with an approved white oil. The 500 TBN allows for increased flexibility in base oil composition and viscosity in the final grease formulation. If properly formulated and processed, the grease will have a high dropping point, excellent water resistance, extreme pressure performance, antiwear performance, and excellent shear stability. Hybase® GFX500 is compatible with most Group I IV base stocks.
APPLICATIONS
Grease feedstock for the manufacture of H-1 calcium sulfonate thickened grease.
TYPICAL TREAT
Nominal dosages would range from 20 to 70 wt.% of the finished lubricant depending on the thickening process and final NLGI grade.
HANDLING INFORMATION
Hybase® GFX500 is a liquid overbased calcium sulfonate and is normally handled at elevated temperatures for improved pumpability. For general purposes, the following storage and handling
temperatures are recommended:
DRUM STORAGE 15-40°C (60-104°F)
BULK STORAGE 60-80°C (140-176°F)
BULK HANDLING 80-90°C (176-194°F)
