• forms an optimal corrosion protection film in the entire system, prevents deposits on pipe walls 
• must not be used in systems containing aluminium or materials containing aluminium 
• shows excellent hardness stabilisation on calcium carbonate and other hardness formers 
• stabilises the water hardness even at points in the process water system that are subject to thermal stress 
• works optimally in the pH range 7.5 to 10

RHOBA SUPRA C301 has a safe corrosion inhibiting effect on carbon steel, copper, copper alloys and non ferrous metals in closed and semi-open cooling and process water systems. 
It can also be used to passivate copper and brass, which allows for up to 4 weeks of indoor storage. 

The dosage depends on many factors, including chloride content, thermal stress, statistical retention time, system equipment, turbidity, alkaline earths and similar. 

The concentration in the process water should be 0.5 to 1% and added at a turbulent point in the system. For passivation, a 1% solution is used at room temperature. Distilled water should be used to avoid residues.

Before use, check material compatibility in an inconspicuous place.

Follow the manufacturer's cleaning and care instructions! No liability can be accepted for improper use and resulting damage.
