Heat treatment has always been a critical process across industries to strengthen metal components. However, today’s industries—especially automotive—demand more than just durability. They seek miniaturization, lightweight materials, and higher strength to meet evolving performance and environmental standards.

At the same time, environmental protection, CO₂ emissions reduction, and workplace safety are becoming essential considerations in manufacturing.

Simply making parts stronger is no longer enough.
We now need sustainable, safe, and highly efficient heat treatment solutions.
That’s why Dyna proudly presents the next step forward: Water-Soluble Coolants and Polymers.

Is Traditional Oil-Based Quenching Still the Best Option?

For decades, oil-based quenching fluids have been the industry standard. They offer:

• Uniform Cooling: Providing steady cooling rates for precise results.
• Corrosion Protection: Creating a protective barrier against oxidation.
• Thermal Stability: Performing reliably even at high temperatures.
• Long-Term Consistency: Maintaining cooling performance over multiple uses.

However, oil-based fluids also come with significant downsides:

• Slower Cooling Speeds: Not ideal for rapid quenching applications.
• Environmental Impact: Risk of contamination and costly disposal requirements.
• Fire Hazard: Flammability issues, especially during high-temperature processes.
• Workplace Cleanliness Issues: Oil residues require complex cleaning and can create messy work environments.

In today’s world, where eco-friendliness and safety are top priorities, many companies are looking beyond oil—and turning to smarter alternatives.

The Smart Alternative: Water-Soluble Coolants and Polymers

Water-soluble polymers are redefining modern heat treatment. These coolants, made from water-soluble polymers mixed with water, offer a superior balance of performance, safety, and sustainability.

Key Benefits of Water-Soluble Coolants:

• Reduced Fire Risk: Being water-based, the fire hazard is dramatically lower than with oils.
• Precise Cooling Control: Adjust polymer concentration to fine-tune cooling speeds, preventing cracks and distortions.
• Eco-Friendly: Less environmental impact and easier waste management compared to oil-based fluids.
• Corrosion Resistance: Special additives help protect metal surfaces from oxidation.
• Cost-Effective: Lower maintenance, longer coolant life, and potential insurance savings.
• Cleaner, Safer Work Environment: Minimal residue on treated parts and a much cleaner shop floor.

How It Works

Using water-soluble polymers is simple:
Mix the polymer with water at a set ratio, adjusting the concentration based on the metal type and specific heat treatment process.
This flexibility makes it ideal for quenching high-grade alloy steels and large components where controlling deformation and cracks is critical.

Thanks to its precise cooling capabilities, water-soluble polymer technology can significantly improve product quality, process stability, and workplace safety.
