Coendurol MEG is a Mono Ethylene Glycol based water soluble liquid which contains effective combination of corrosion inhibitors. It offers excellent protection against corrosion for different metals in coolant circuits e.g. Aluminum, Steel, Non ferrous metals, brass,copper.
Area of application for Coendurol MEG:
A suitably diluted solution of coendurol with distilled water can be used for
- Refrigeration Systems
- Various industrial cooling systems
- Process cooling Heating
- Plastic extrusion, Spindle cooling, Plasma cooling etc
- Automotive
Application Methods of Coendurol MEG:
Coendurol MEG is typically diluted as per requirements. A minimum dilution of 20 is used in application areas. Systems previously used with salt-based coolants or chloride rich brines must be thoroughly flushed with water otherwise the corrosion inhibiting effect of the product will be impacted. Any other type of coolant being circulated in the closed circuits should be kept completely separate.
Similarly, any system used with coendurol should be thoroughly flushed with water. Any empty systems should be thoroughly inspected before filling with Coendurol MEG-water mixture.
Determine degree of freeze protection
To achieve the desired freeze resistance, Coendurol MEG is mixed with water. The water used to dilute Coendurol MEG shall contain no more than 100 mg/kg (ppm) chlorides.
The mixing ratio is calculated as follows:
| Freeze Protection Temperature (C) |
Concentration (vol%) |
Density at 20 C (g/cm) |
| -9 C |
20 vol% |
1.027 |
| -12 C |
25 vol% |
1.034 |
| -20 C |
35 vol% |
1.046 |
| -53 C |
60 vol% |
1.078 |
The ratio of Coendurol MEG must be at least 20% by volume (corresponds to freeze
protection down to - 9 C) in order to obtain a sufficient corrosion protection.
