DESCRIPTION
Hybase® C-502 is a 500 TBN oil soluble overbased calcium sulfonate. It provides the highest TBN of calcium carbonate available in a liquid, oil based format. Hybase® C-502 is typically used as a detergent and rust inhibitor in crankcase lubricants. It is designed as both a stand alone detergent as well as in conjunction with other detergent types such as calcium phenate. It is also suitable for thickening Calcium Sulfonate grease. Hybase® C-502 is compatible with most Group I, II, III, and IV base stocks.
APPLICATIONS
Automotive, diesel, marine, railroad and stationary diesel lubricants as well as industrial lubricants and grease.
TYPICAL TREAT
Nominal dosages would range from 0.5 to 30.0 wt.% of the finished lubricant.
HANDLING INFORMATION
Hybase® C-502 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)
