DuraKut 450

Metalworking coolant DuraKut 450 is a high-performance, semi-synthetic metal removal fluid formulated for modern manufacturing processes. It combines the cooling properties of a semi-synthetic fluid with the boundary lubrication benefits of soluble oil. Designed for a wide range of machining operations, it works efficiently on both ferrous and non-ferrous metals, including aluminum, brass, copper, and steels.

Key Features & Benefits:

1. Lubricity & Tool Life:

• • Contains a superior lubricity package, extending tool life.
  • Permits increased feeds and speeds, even for medium to heavy-duty metal removal operations.
  • High-temperature and extreme-pressure lubricants activate as feed rates increase, ensuring outstanding machining performance.

1. Corrosion Protection:

• • Provides excellent protection against galvanic corrosion, especially in iron-copper and iron-aluminum conductivity environments.
  • Includes specialized corrosion inhibitors to prevent staining and ensure superior finishing for non-ferrous metals like aluminum, brass, and copper.

1. Operational Stability:

• • Hard water stable and maintains emulsion stability across varying water conditions.
  • Low foaming formulation ensures reliable performance, even at high pressures.
  • Clean-running, enabling transparent observation of the workpiece during operations.

1. Environmental & Operator Safety:

• • Bio-stable formulation prevents the growth of bacteria and fungus, reducing maintenance needs.
  • Non-flammable and operator-friendly, making it suitable for a range of industrial settings.

Typical Properties:

1. Appearance (Neat): The fluid appears as an amber-colored liquid when undiluted.
2. Appearance (Diluted): When mixed with water, the fluid becomes a transparent liquid.
3. Odor: The fluid has a mild odor, ensuring operator comfort during use.
4. Specific Gravity: Ranges from 0.99 to 1.01 g/mL, ensuring consistent density.
5. pH (at 20:1 mix with water): The pH level typically falls between 9.2 and 9.5, providing a stable and alkaline environment.
6. Flash Point: The product does not have a flash point, indicating it is non-flammable.
7. Effect of Freeze-Thaw Cycle: The fluid remains stable even after undergoing freezing and thawing.
8. Refractive Index Factor: The refractive index factor is 1.67, which is used for monitoring and adjusting fluid concentration.

Applications:

DuraKut 450 is suitable for various machining and grinding operations, including:

• General machining.
• Tapping, reaming, and threading.
• Sawing and grinding.

Its balanced formulation ensures effective cooling and lubrication for operations of all severity levels.

Concentration Control:

Maintaining the correct concentration is essential for performance:

1. Use a handheld refractometer to measure the concentration.
2. Multiply the refractometer reading by the Refractive Index (RI) Factor (1.67) to determine the actual concentration.
3. Adjust as necessary:

• • Add water to reduce concentration.
  • Add product concentrate to increase concentration.
