Description

Cupro is a liquid, organic corrosion inhibitor and is used for corrosion protection of copper and copper alloys in recirculating cooling water, heating and district heating systems.

Operation
The operation of cupro is in twofold:
1. cupro forms a good, contiguous and corrosion-protective film layer, which consists of a chemically highly stable cuprous copper complex on the metal surface.
2. Copper ions in solution, due to corrosion, create copper deposits on materials (copper plating). Copper Plating can cause serious corrosion and damage on iron, steel and aluminum in particular. Cupro is able to form insoluble complexes with copper ions, so that these materials can be protected from copper plating, and so galvanic corrosion.

Dosage instructions
For closed heating and district heating systems:
- The starting dose is 400 ml / m3 system content (200 ppm).
- The maintenance dose is 200 ml / m3 of water supplementation.
Cupro can be added without difficulty to alkaline water treatment products and are therefore dosed into the system in conjunction with this product by means of a metering pump. Cupro can not be mixed with neutral- or acid products.

For recirculating cooling systems
The dosage is dependent on the operational parameters of the cooling system on.

Precautions
Cupro contains, 2-4% sodium hydroxide solution and is highly alkaline. Wear chemical-resistant gloves and eye or face protection. In the case of spillage on clothes or skin, rinse immediately with plenty of water. If Cupro comes into contact with eyes, contact a doctor.
Spillage using sand or other absorbents and dispose of as chemical waste. Where spill clean with plenty of water, flushing water discharged into the drain.
