Directions for use
Rocor NB Liquid is a highly effective corrosion inhibitor for the common ferrous and non-ferrous metals in cooling water systems.
The stable oxide film that is formed prevents corrosion caused by electrolytic action between dissimilar metals used in the system.
Rocor NB Liquid has been field tested and found to have no detrimental effects on non metallic substances such as seals, glands, packing, hoses, gaskets etc., normally used in these systems.
The compound is alkaline and so will suppress acid corrosion, which would otherwise result in corrosion damage such as pitting. However, the alkalinity control is such that even if the product is accidentally overdosed, the pH of the water will remain within limits. The metals which would be affected by extremes of alkalinity or acidity are protected.
In cases where systems are contaminated with oil and/or scale they should be cleaned before starting to apply Rocor NB Liquid. There are suitable Unitor products to carry out the cleaning. Degreasing should be carried out using Seaclean Plus and descaling by using Descalex. Refer to Water Treatment handbook.
The use of antifreeze is sometimes required if the vessel is to be laid up in cold areas and so Rocor NB Liquid can be used in conjunction with antifreeze products.
If the system contains galvanized parts, it is advisory to clean the system with Descalex prior to commencing the treatment.
Caution: This product should not be used in systems containing aluminium parts in cooling water spaces!
