CA 400 is an overbased calcium sulfonate, and EP/AW, and corrosion inhibitor component for use in corrosion preventives, metalworking fluids and lubricants. It is non staining and odour free. The product is also suited for use as TBN booster.
CA 400 has high reserve basicity and therefore neutralizes corrosive acids. In corrosion preventives concentrations of 1-20% CA 400 can be used depending on the application. In metal forming operations for ferrous and non ferrous metals 5-10% are recommended. 20-30% CA 400 can be employed for heavy duty drawing operations. A combination with sulphur compounds may be useful.
Tightly closed drums can be stored indoors between 0°C and 40°C for a mini-mum of 12 months.
