TMC-649 Engineered Fluid is a direct replacement for, and is miscible with 3M Novec® 649.

TMC-649 is a clear, colorless and low odor fluid designed as a replacement for ozone depleting substances (ODSs) and compounds with high global warming potentials (GWPs) such as sulfur hexafluoride (SF6) and hydrofluorocarbons (HFCs), such as HFC-134a and HFC 245fa. TMC-649 is an advanced heat transfer fluid, balancing customer needs for physical, thermal and electrical properties, with desirable environmental properties.

APPLICATIONS

TMC-649 is a chemically identical replacement for 3M Novec™ 649 with specific properties suitable for heat transfer applications where non-flammability and environmental concerns are important.

• Electronics Cooling (Dual Phase) 
• Computer/Data Center Cooling
• Power Electronics such as IGBTs or inverters Generators
  
• Solar Applications
• Transformers and other equipment 
• Heat Transfer

PHYSICAL PROPERTIES COMPARISON

STABILITY

TMC-649 should be used in a sealed system to prevent interaction with water, however it is remarkably stable in its absence to over 300°C. 

STORAGE & HANDLING

Store at temperatures not exceeding 38°C/100°F  Store away from strong bases.  Store away from amines.  Protect from sunlight, and store in a well-ventilated place.

SHELF LIFE & STORAGE

Shelf life is 60 months from the date of manufacture when stored in the original packaging materials and stored under normal conditions. TMC will re-certify material every 5 years up to 20 years.  

MATERIALS COMPATIBILITY

Experiments show that TMC-649 with other materials, such as rubber, metal, has good compatibility, and little impact on a variety of materials used. Though TMC-649 with metal contact 10 days under 48 °C, no fade or damage trace is found.

Incompatible Materials:  Strong bases, amines, and alcohols
