3M Novec7500 Electronic fluorination solution Cas 297730-93-9

Introduction

3M™ Novec™ 7500 Engineered Fluid is a nonflammable fluid with very low global warming potential for 
use in heat transfer applications. Novec 7500 fluid shares many of the inertness and dielectric properties of 
perfluorocarbons (PFCs) and perfluoropolyethers (PFPEs), and is a viable option for replacing them in a wide 
array of applications

Semiconductor

This Novec fluid can be used in cooling of ion implanters, dry etchers and CVD machines in semiconductor and 
flat panel display manufacturing facilities.

Test Equipment

The fluid may be used to cool semiconductor thermal shock and test equipment.

Electronic Cooling

Because Novec 7500 fluid is compatible with most electronic components, it can be used in direct contact 
single- and two-phase cooling of supercomputers and sensitive military electronics, and to cool high voltage 
transformers and power electronics.

Industrial/Pharmaceutical

Novec 7500 fluid can also be used as an alternative to commonly used fluids in pharmaceutical and chemical 
manufacturing processes, such as freeze drying and reactor cooling.
The primary advantage of Novec 7500 fluid over a comparable PFC or PFPE, however, is reduced Global 
Warming Potential (GWP). Novec 7500 fluid has been developed as a low-GWP alternative to perfluorocarbon 
and perfluoropolyether heat transfer liquids. 
Novec 7500 fluid is non-ozone-depleting and has been exempted from the U.S. EPA definition of a volatile 
organic compound (VOC) because it does not contribute to the formation of photochemical smog

Typical Physical Properties

Novec 7500 Fluid Kinematic Viscosity

To determine the viscosity at a given temperature T in Kelvin, calculate 
Z = 10^( 10^( 11.843-5.0874*Log(T[K]) ) ). 
Then, Viscosity [cSt] = (Z-0.7) - exp(-0.7487 - 3.295(Z-0.7) 
+ 0.6119(Z-0.7)2
 - 0.3193(Z-0.7)3 )

Typical Physical Properties (continued)

Toxicity Profile
The toxicological testing completed on 3M™ Novec™ 7500 Engineered Fluid indicates very low overall toxicity. 
The material is minimally irritating to the skin and eyes and tested negative in two mutagenicity screens. 
In its intended applications a large margin of safety exists between anticipated exposure and the eight hour 
time weighted average exposure guideline of 100 ppm. In a 28-day oral toxicity study no adverse effects were 
observed at 1000 mg per kg body weight.

Environmental, Health and Safety

Before using this product, please read the current product Material Safety Data Sheet (available through your 
3M sales or technical service representative) and the precautionary statement on the product package. Follow 
all applicable precautions and directions. 3M™ Novec™ 7500 Engineered Fluid is nonflammable and does not 
exhibit flammability characteristics under normal operation and storage conditions. The fluid is resistant to 
thermal breakdown and hydrolysis during storage and use. Recommended handling procedures are provided in 
the Material Safety Data Sheet, which is available from your local 3M representative upon request.

Materials Compatibility

In practice, Novec engineered fluids differ somewhat from PFCs and PFPEs in their ability to dissolve certain 
oils. This means that Novec 7500 fluid is more likely to extract plasticizers from elastomeric materials. For 
this reason, elastomeric O-ring and seal materials should be limited to those that contains a low amount of 
plasticizer. EPDM, EPR and butyl typically fall into this category. 3M engineers can suggest appropriate 
compounds or assist with test procedures.

Heater Selection

The critical heat flux of Novec 7500 fluid was found to be 18 W/cm2
 when boiling from a horizontal 0.5 mm 
diameter platinum wire in a quiescent pool of saturated fluid. The maximum heat flux obtainable in forced 
convection applications is significantly higher, but depends strongly upon the geometry and flow conditions. 
A safety interlock between the pump and heater is strongly recommended in applications with heat fluxes 
exceeding 15 W/cm2
.
Regulatory Status

The components of this product are in compliance with the chemical notification requirements of the 
United States (TSCA), Europe (ELINCS), Korea and the Philippines. Novec 7500 fluid is not acceptable for 
commercial sale in Japan. Certain restrictions apply. Contact the selling division for additional information.
Contact your local 3M representative regarding the regulatory status of Novec 7500 fluid in other countries.

Recycle and Disposal Options
Used Fluid Return Program
