Directions for use

• NALFLEET™ 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. NALFLEET™ 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 NALFLEET™ Rocor NB Liquid. There are suitable WSS products to carry out the cleaning. Degreasing should be carried out using UNITOR™ Seaclean Plus and descaling by using UNITOR™ Descalex. Refer to Water Treatment handbook. Freeze protection can be required if the vessel is to be laid up in cold areas. NALFLEET™ Rocor NB Liquid can be used in conjunction with glycols to provide suitable freeze protection. If the system contains zinc galvanized parts, it is advisory to clean the system with Descalex prior to commencing the treatment.
