GCK199

API CD WITH 11 TBN

Description

GCK199 is a minimum treatment rate cost effective package designed to cover API CD performance giving a 10TBN and US military performans for combind engine gearboxes.

Special Features

GCK199 has been formulated for use in traditional group I base oil for applications that require high TBN and to lubricate heavy duty diesel applications where combined engine and gear lubricants are required. It is especially suitable where diesel fuel carries more sulphur than the 25 ppm mandated in Europe.

Applications

GCK199 is used at the treatment levels shown in the following table. It is blended with mineral base oil, a pour point depressant and optionally a polymer to make a multigrade, according to blending procedure guidelines available.

General Storage and Handling

Minimize decomposition and/ or hydrogen sulphide evolution, do not blow or mix whit wet gas, prevent any contact with water. Facilities should be designed to handle ZDDP’s without heating. If heating is required, a careful review is essential to insure

That the product is not overheated as overheating can result in hydrogen sulphide, mercaptan and olefine evolution due to ZDDP decomposition.

The product may be blended and handled at temperatures up to 140 ̊F (80 ̊C) but long term storage at temperatures higher than 100 ̊F (40 ̊C) should be avoided.

Air contanct with heated product should be avoided it may result in a discoloration.
