It prevents corrosion of all metals found in these systems i.e. ferrous metals copper and copper alloys and aluminium. It is suitable for all types of boiler radiators and pipework systems. Fernox Protector MB-1 is compatible with all metals and materials commonly used in central heating systems. For continued protection we recommend Protector levels are checked regularly (annually). The concentration of the product can be easily measured on site using a Fernox Protector test kit. Physical Properties Protector MB-1 is a blend of inorganic and organic corrosion and scale inhibitors and biocide. Colour: Pale. Amber. Odour: Faint Form: Liquid pH (conc.): 8.3 – 8.8 pH (4% soln): 8.2 – 8.6 SG: 1.025 at 20°C Application and Dosage The recommended ‘in-use’ concentration of the product is 4%. One 4 litre pack will treat an average 3 to 4 bedroom house. The product can be introduced via the feed and expansion tank or injected directly into the system via a radiator or filling loop. In single feed indirect cylinders e.g. "Primatic" or similar potable water chemicals must be used. We recommend untreated systems are thoroughly cleansed and flushed in accordance with BS7593 and Benchmark using Fernox Restorer before treating with Fernox Protector MB-1 as existing debris can damage the installation. Packaging Handling and Storage Fernox Protector MB-1 is supplied in 4 litre and 25 litre containers. Fernox Protector MB-1 is classified as non-hazardous but as with all chemical: Keep out of reach of children. Do not mix with other chemicals. Do not take internally.
