Cortec VpCI® additives for formulators: M-640

M 640 is an additive for engines using water and ethylene glycol. It protects engines and their components during heat exchange from the detrimental effects of corrosive contaminants.

This additive can protect both ferrous and non-ferrous metals.

Unlike traditional phosphate/nitrite-based or amine compounds, M 640 presents a more advanced and efficient solution. Its innovative organic-inorganic composition makes it a perfect substitute. Despite a substitute, the additive can still deliver superior results without compromising on effectiveness.

The real magic of M 640 lies in its carefully crafted blend of contact and vapuor phase corrosion inhibitors. This unique combination endows the additive with remarkable corrosion protection properties, even in partially filled spaces.

Engineers and maintenance professionals in industrial settings can rely on M 640. This liquid additive can do a lot of things. One, it preserves the integrity of machinery. Two, it optimises operational efficiency. Lastly, the liquid can reduce the risk of costly downtime caused by corrosion-related issues. It is your gateway to unrivalled protection for crucial systems and components.

Typical Applications:

Alternative to Traditional Inhibitors
One of the typical applications of M 640 lies in its role as a cutting-edge alternative to traditional corrosion inhibitors. By incorporating M 640 into antifreeze/coolant formulations, formulators can achieve the desired corrosion protection without the harmful effects of nitrites, phosphates, and amines. This aspect makes it particularly beneficial for automotive and industrial cooling systems, where long-term and efficient protection is vital.

Automotive and Heavy Machinery
Moreover, M 640 exhibits exceptional versatility, enabling its use across various industries, including automotive, heavy machinery, power generation, and more. The recommended operating concentration range of 0.5-0.8% by weight ensures optimum performance, preventing under or over-dosing scenarios.

Mitigate Environmental Concerns
Another crucial application of M 640 is its ability to mitigate environmental concerns associated with traditional corrosion inhibitors. Being free from harmful chemicals, it promotes eco-friendly coolant solutions, aligning with sustainable practices and stringent environmental regulations.

Thermal Efficiency of Systems
Formulators can confidently rely on M 640 to enhance the thermal efficiency of cooling systems while safeguarding components from pitting, cavitation, and galvanic corrosion. This results in improved heat transfer rates and overall system reliability, minimising maintenance costs and downtime.

Packaging and Storage
M- 40 comes in 100-pound (45 kg) drums with a polyethylene lining. Ensure to store it in a tightly sealed container within a dry warehouse, away from direct sunlight, and maintain temperatures below 150ºF (66ºC). When stored under these recommended conditions, the product can have a shelf life of up to 24 months.
