Introduction:

TMC-7300E is a replacement fluid for 3M™ Novec™ 7300.  It is a clear, colorless, odorless fluid that has utility in a wide variety of applications, including heat transfer, lubricant deposition, electronic testing, and cleaning applications. This product is non-flammable, thermally stable, non-ozone depleting, and has a very low global warming potential. It does not contribute to the formation of photochemical smog. It is recommended for use as a replacement for perfluoropolyethers (PFPEs), perfluorocarbons (PFCs), hydrochlorofluorocarbons (HCFCs), and hydrofluorocarbons (HFCs). Excellent safety profile backed by 3rd party testing for Non-Detectable PFAS, this product is the ideal replacement for Ozone-depleting substances. With its wide range of applications and non-flammable nature, it offers the perfect balance of performance and protection.

On this basis, it provides a useful tool to help meet commitments for greenhouse gas emission reduction. The boiling point, wide liquid range, and low-temperature viscosity of this product make it ideal for cooling ion implanters, dry etchers, and CVD machines. It is effective at mitigating the aggressiveness of solvents and is useful in inerting the flammability of blends. The chemical and thermal stability of this product lends to its use as a reaction media. 

TMC-7300E is equivalent to 3M™ Novec 7300.
