描述
3M Novec 71D90 Engineered Fluid Aerosol Cleaning Solvent
Type: Aerosol Cleaning Blend
Composition: 90% t-DCE / 10% HFE
Boiling Point: 42.6°C
GWP: 32
Packing: 5 kg / 20 kg drum
3M Novec 71D90 Engineered Fluid is a high-solvency blend of 90% trans-1,2-dichloroethylene (t-DCE) and 10% methyl nonafluorobutyl ether (HFE-7100). Designed specifically for aerosol cleaning formulations, this mixture exhibits azeotrope-like behavior with a depressed boiling point of 42.6°C. Novec 71D90 offers excellent solvency as a replacement for HCFC-141b in aerosol cleaners, delivering zero ozone depletion potential and an ultra-low GWP of 32 — one of the lowest among cleaning solvents. The high t-DCE content provides increased formulating flexibility for precision cleaning applications.
Novec 71D90 is nonflammable with no closed cup flashpoint under normal storage conditions. However, due to the differential evaporation rates of its components, the composition will change during evaporation, potentially creating a flammable liquid. Therefore, this product is not recommended for vapor degreasing or cold cleaning baths — it is intended exclusively for aerosol cleaning formulations. With t-DCE not classified as a Hazardous Air Pollutant (HAP), Novec 71D90 offers a favorable regulatory profile compared to traditional chlorinated solvents.

Frequently Asked Questions
What is 3M Novec 71D90 Engineered Fluid?
3M Novec 71D90 is a blend of 90% trans-1,2-dichloroethylene and 10% methyl nonafluorobutyl ether. It is specifically designed for aerosol cleaning formulations, offering excellent solvency with zero ozone depletion potential and ultra-low GWP of 32.
Why is Novec 71D90 not recommended for vapor degreasing?
Novec 71D90 will not maintain constant composition during evaporation due to differential evaporation rates of its components. Evaporation may change the composition, resulting in a potentially flammable liquid. Therefore, it is not recommended for vapor degreasing or cold cleaning baths.
What is the GWP of Novec 71D90?
Novec 71D90 has an ultra-low global warming potential (GWP) of 32 (100-year ITH), making it one of the lowest GWP cleaning solvents available.
Is Novec 71D90 flammable?
Novec 71D90 has no closed cup flashpoint and is nonflammable under normal storage conditions. However, evaporation can change composition and potentially create a flammable liquid, so it is not recommended for open bath applications.
What applications is Novec 71D90 suitable for?
Novec 71D90 is intended for aerosol cleaning formulations, replacing HCFC-141b in many aerosol cleaners. Its high t-DCE content (90%) provides increased formulating flexibility for precision cleaning applications.
Is Novec 71D90 a VOC or HAP?
t-DCE is designated as a VOC but is not considered a Hazardous Air Pollutant (HAP), making it less regulated than other chlorinated solvents like trichloroethylene or perchloroethylene.
