Hybase ® C-311

DESCRIPTION

Hybase® C-311 is a 300 TBN oil soluble overbased calcium sulfonate. Hybase® C-311 is a typically used as a detergent and rust inhibitor in crankcase lubricants. It can be used as the sole detergent but will also work well in conjunction with other detergent types, such as calcium phenate. Hybase® C-311 is compatible with most mineral base oils, white oils, and synthetic base stocks.

APPLICATIONS

Automotive, diesel, marine, railroad and stationary diesel lubricants.
