3M™ Novec™ 71IPA Engineered Fluid

3M™ Novec™ 71IPA Engineered Fluid

Sometimes you need the best of both worlds. 3M™ Novec™ 71IPA Engineered Fluid combines the cleaning power of isopropanol with the non-flammability of hydrofluoroether (HFE) chemistry.

Like isopropanol (also known as isopropyl alcohol or rubbing alcohol), Novec™ 71IPA provides effective light-duty removal of oils, greases, waxes and fingerprints. Unlike isopropanol, Novec™ 71IPA is non-flammable and significantly reduces the risk of fire hazards associated with isopropanol.

This non-flammable solvent evaporates quickly without leaving any residue, making it an effective rinsing and drying agent. Faster drying times lead to increased productivity.

Novec™ 71IPA Engineered Fluid is non-flammable, non-ozone depleting, and has a low global warming potential, making it an environmentally friendly choice for precision cleaning and surface preparation.

3M™ Novec™ 71 IPA is also effective when combined with co-solvents for “no-clean flux” residue removal from printed circuit boards and other electronics. Its low surface tension helps Novec™ 71IPA with cleaning hard-to-reach areas, ensuring that all contaminants are removed.

What is Novec™?

Novec™ is a brand of engineered fluid developed by 3M™ for use in vapor degreasing and precision cleaning. Novec™ fluids use hydrofluoroether (HFE) chemistry, and are non-flammable, low toxicity replacements for CFCs, HCFCs, HFCs, n-propyl bromide (nPB) and chlorinated solvents.

What is Novec™ 71IPA? – Features & Benefits

3M™ Novec™ 71IPA is an azeotropic blend designed for light-duty cleaning or vapor degreasing of a wide variety of materials, including metal, glass and some plastics and elastomers. In a materials compatibility study of additive manufacturing cleaning, Novec™ 71IPA scored highest with all ten materials tested, making it the solvent of choice for AM component cleaning.

The chemical composition of 3M™ Novec™ 71DA is a hydrofluoroether (HFE) blend with isopropanol. The HFE portion of the blend consists of two inseparable isomers of methyl nonafluorobutyl ether (C₄F₉OCH₃) with essentially identical properties. These are (CF₃)₂CFCF₂OCH₃ (CAS 163702-08-7) and CF₃CF₂CF₂CF₂OCH₃ (CAS 163702-07-6).

Novec™ 71IPA is especially useful where the cleaning effectiveness of isopropanol is desired, without the fire hazard risk. Novec™ 71IPA features low surface tension, non-flammability and fluid stability. This stable blend has essentially constant vapor and liquid composition at its boiling point, and Novec™ 71IPA can be used in a wide range of vapor degreaser types.

Novec™ 71IPA offers high materials compatibility and effective cleaning quality in a solvent with an excellent safety profile. Novec™ 71IPA benefits are particularly useful for cleaning medical device parts, electronic components, optical lenses and aerospace parts during production.

• Effective light-duty cleaning of greases, oils, waxes and fingerprints
• Stable, azeotropic solvent blend
• Low global warming potential (GWP)
• Zero ozone depletion potential (ODP)
• Non-flammable
• Low toxicity makes it safe for workers and the environment
• Low surface tension allows it to penetrate tight spaces for thorough cleaning

3M™ Novec™ and 3M™ Fluorinert™ Voluntary Phase Out

With the final order deadline for 3M™ Novec™ and 3M™ Fluorinert™ now behind us, product availability is rapidly declining. We continue to receive 3M™ Novec™ and 3M™ Fluorinert™ fluids when available and will advocate for fulfillment of outstanding orders. However, it is now critical to transition. We strongly recommend beginning validation and testing of BestSolv® replacement fluids to ensure uninterrupted operations.

3M™ Novec™ 71IPA Replacement Fluid – BestSolv® 71IPA or BestSolv® Lima

Realizing our customers must transition away from 3M™ Novec™ 71IPA, Best Technology offers BestSolv® 71IPA as a 3M™ Novec™ 71IPA exact molecule replacement, or BestSolv® Lima as a 3M™ Novec™ 71IPA similar molecule, drop-in replacement, based on the 3M™ announcement of the Novec™ fluid phase out in 2022.
