MEC CLEAN 2.5: The “Non-Oil” Revolution in Cutting and Metal Removal

Imagine opening your machining center door and no longer smelling the sharp odor of burnt oil. It’s not a trick of the senses—it’s the innovation of CLARIL MEC CLEAN 2.5, a heavy polymer-based coolant that removes mineral oil from the production process.

The concept is simple:
No Oil = No Dirt.

Chemical and physical characteristics:

• Appearance: clear liquid, tending toward transparent.
• Total solubility: unlike traditional emulsions that turn white, MEC CLEAN 2.5 mixes instantly with water while remaining transparent. It never separates, eliminating the need for aggressive chemical emulsifiers.
• Management of tramp oils: Guideway oils that contaminate the tank float on the surface without binding to the product. This makes them easier to remove and prevents bacterial growth, ensuring an exceptionally long fluid life.

Competitive advantages for your workshop

1. Cleaning and post-process operations

Because the coolant emulsion contains no oil, metal particles do not adhere to the workpiece surfaces. Chips fall off easily and can be removed with a simple blast of air.
This is essential for cleaning the interior of complex tubes or profiles, which remain clean after each process.

2. Welding and laser cutting “without washing”

The high temperatures of laser cutting or welding burn oily residues, creating fumes and defects. MEC CLEAN 2.5 leaves no greasy residues: this ensures superior joint quality and allows the washing step to be skipped, delivering immediate cost savings in the production cycle.

3. Multi-material versatility

There are certain materials where maintaining cleanliness during processing is especially important:

• Aluminum: it does not stain or dirty, and parts are ready for assembly or bonding.
• Thermoplastics (or carbon fiber): ideal for delicate materials that would be damaged by the surfactants in conventional emulsions. No oily residues, no dirt, and no chemical attack on surfaces.

4. Safety and environment

Although the concentrated product requires standard precautions, it may still be irritating to the skin if used without protective gloves. However, once diluted in water at the appropriate working concentrations, its impact on operator health and the environment is drastically lower compared to conventional lubricants rich in surfactants.

The Bio alternative: CLARIL ESTERMEC BIO 6

If your process still requires an oil-based product but you want to overcome the limitations of mineral oil, the solution is to use a high-quality ester-based lubricant.
Vegetable esters deliver superior performance and significantly improve environmental compatibility.

Advantages of ester-based oils:

• Extreme resistance: better stability at high temperatures and under extreme pressure (EP conditions).
• Workshop safety: reduced release of mist and gases during cutting.
• Tool protection: longer tool life for drills and inserts thanks to the stability of the lubricating film.

ESTERMEC BIO 6 is our biodegradable multi-metal coolant, resistant to bacterial contamination and ideal for those seeking cleanliness and performance in a single product.

Technical Tip: To maximize the shelf life of any oil-based emulsion, we recommend using a high-quality volumetric mixer.
During use, since emulsions tend to self-concentrate, it is important to monitor the emulsion to ensure it remains at the correct concentration. A refractometer is required for this task.

Which one to choose for your workshop?

• Choose MEC CLEAN 2.5 (Polymers) if:
  • You want to permanently eliminate the cost of washing parts before welding.
  • You work with many different materials, including thermoplastics.
  • Your priority is absolute cleanliness of the working environment and fluid transparency to monitor the cutting process.
• Choose ESTERMEC BIO 6 (Esters) if:
  • You perform heavy-duty machining operations under high pressure (EP), where maximum lubricating performance is required.
  • You are looking for a bio-based solution that protects the most expensive and delicate tools.
  • You prefer a traditional lubricant but with performance and sustainability clearly superior to mineral oil.
