Introduction

replacements for ozone depleting substances (ODSs) and compounds with high global warming potentials (GWPs)

3M Novec 649 Engineered Fluid is an advanced heat transfer fluid, balancing customer needs for physical, thermal

and electrical properties, with desirable environmental properties.

Typical Applications

Novec 649 fluid is an effective heat transfer fluid with a boiling point of 49ºC. Novec 649 fluid is useful in heat

transfer particularly where non-flammability or environmental factors are a consideration.

Examples of systems which benefit from use Novec 649 fluid include:

Dodecafluoro-2-methylpentan-3-one
