Coendurol MPG is a Mono Propylene Glycol-based, water-soluble fluid developed to provide exceptional corrosion protection and efficient heat transfer across a range of cooling systems. Its formulation includes an effective blend of corrosion inhibitors that protect various metals, including aluminum, steel, brass, copper, and non-ferrous metals, ensuring durability and extended lifespan of cooling systems and equipment.

This information page explores Coendurol MPG's features, areas of application, methods of use, and guidelines for ensuring effective freeze protection.

Features of Coendurol MPG

Coendurol MPG is engineered to meet the demanding requirements of systems where efficient heat transfer and corrosion prevention are critical.The products core features include:

(i).Mono Propylene Glycol Base: Coendurol MPG is based on Mono Propylene Glycol, a non-toxic and environmentally friendly substance that provides excellent freeze protection and corrosion resistance.

(i). Corrosion Protection: Its blend of corrosion inhibitors safeguards metals like aluminum, steel, brass, copper, and non-ferrous metals from oxidative damage in coolant circuits.

(i). Heat Transfer Efficiency: The product functions as a highly effective heat transfer fluid, helping to regulate temperatures and prevent overheating or freezing in various systems.

Area of application for coendurol:

A suitably diluted solution of coendurol MPG 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:

Coendurol MPG is typically diluted as per requirements. A minimum dilution of 25 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 -water mixture.

Freeze Protection and Mixing Ratios

One of the essential characteristics of Coendurol MPG is its ability to provide freeze protection, which is determined by the concentration of the solution. To achieve the desired freeze protection level, Coendurol MPG must be mixed with water, ensuring that the water contains no more than 100 mg/kg (ppm) of chlorides. Below is a table showing the freeze-protection levels based on Coendurol MPG concentration.

The mixing ratio is calculated as follows:

Freeze-Protection Temperature (C)	Coendurol Concentration (vol%)	Density at 20C (g/cm)
-10C	25%	1.022
-17C	35%	1.030
-33C	50%	1.040
-44C	57%	1.044

These characteristics offer guidance on the expected behavior and performance of Coendurol MPG under normal operational conditions. It is recommended to refer to the safety data sheet for further details on product properties, toxicological, ecological, and safety data.
