WOUCOOL 769 is a fully synthetic black metal machining fluid with high cleanliness and cooling performance. Superior rust prevention performance provides sufficient rust protection for workpieces, equipment, and fixtures. This product is suitable for grinding processing of cast iron, carbon steel, engineering plastics, and alloy steel, such as centerless grinding, external cylindrical grinding, and surface grinding. It can also be used for low load cutting processing of the above materials.
◆ Long service life and excellent biological stability.
Excellent cleanliness and wettability ensure the good working condition of the grinding wheel, while also having good cooling effect, extending the service life of the grinding wheel, and ensuring the quality of the processed surface.
◆ The product does not contain mineral oil. It uses "block polyether" to provide lubrication and reduce grinding metal heat. The product has good anti impurity oil performance, low foam and good visibility of the processing surface.
Excellent rust prevention performance, providing excellent rust protection for workpieces, equipment, and fixtures.
Good settling performance and stable pH, the working fluid can maintain excellent working performance for a long time, reducing the frequency of fluid replacement.
The product is healthy and environmentally friendly, without harmful ingredients such as phosphorus, sulfur, nitrite, diethanolamine, formaldehyde, etc.

·Not recommended for aluminum alloy processing.
· Do not mix directly with oily products.
· When the working concentration of this product is controlled above 5%, its tank life and rust prevention effect are more guaranteed. For processing cast iron parts, the recommended concentration is>6%.
· When the rust prevention requirement between processes is more than 7 days, it is recommended to have a concentration>10%. For more stringent rust prevention requirements between processes, it is recommended to soak the workpiece in a pre prepared solution (concentration>20%) after processing and remove it for storage.
· If you need more product application information, including performance optimization. Please call our staff for consultation.

1. When diluting, it is recommended to use clean tap water and avoid mixing it with other coolant to prevent performance deterioration.
2. For the initial liquid preparation, the concentration should be appropriately increased. The concentration of the working fluid should be monitored and controlled within a reasonable range. If the machine tool does not start for many days, the tank fluid should be regularly circulated and oxygenated.
3. The comprehensive evaporation rate of water, concentration of working solution, supplementary water and concentrated solution.
4. Pour the concentrated solution into an appropriate amount of water, stir evenly, and then add it to the equipment.
5. When using (replacing) new liquid, the equipment should be cleaned first, and it is recommended to use Wenou machine tool cleaning agent.
6. The machine tool should have a complete filtration and slag removal system to promptly remove impurities such as metal shavings and floating oil.
