Effective, sustainable chemistries for an increasingly-regulated world
In the mid-1990s, an international environmental treaty known as the Montreal Protocol mandated the phaseout of ozone-depleting substances (ODSs), such as chlorofluorocarbons (CFCs), hydrochrolorfluorcarbons (HCFCs) and halons. Used in applications ranging from refrigeration and precision cleaning to fire protection, these materials had been industry mainstays for years, and news of their impending phaseout sent users scrambling for alternatives.
It was in response to the need for viable ODS replacement chemistries that the first 3M™ Novec™ Products were born. Today, as the focus of international regulatory activity has shifted to global warming and other issues affecting worker health, safety and the environment, the expanding line of Novec products continues to offer effective, sustainable solutions in a wide range of industrial applications.
Following is a summary of the key regulatory compliance issues that Novec products are helping to address – while still providing the level of performance you need to stay competitive.
3M™ Novec™ Engineered Fluids
Novec fluids have been approved for use as replacements for ozone depleting substances by the U.S. Environmental Protection Agency's (EPA) Significant New Alternatives Policy (SNAP) Program. SNAP lists 3M™ Novec™ 7100 and 7200 Engineered Fluids, and components of their azeotropes, as "acceptable without restrictions" for use in precision cleaning, electronics cleaning, metal cleaning and aerosol solvent applications.
Novec 7000, 7100, 7200, 7300, 7500, and 8200 have been excluded by the U.S. EPA from the definition of a VOC because they have negligible contribution to tropospheric ozone formation.
Novec 7200 fluid and Novec 8200 fluid have received the Clean Air Solvent Certificate from the South Coast Air Quality Management District (SCAQMD)
Novec fluids are accepted by regulatory agencies around the world as alternatives to HCFC-225 and HCFC-141B. And, because they are nonflammable, low in toxicity and are generally recognized as sustainable replacements for those solvents targeted for phase-out by international bodies, Novec fluids are also ideal candidates to replace materials such as trichlorethylene, methylene chloride and n-Propylbromide (nPb).
Novec fluids are widely used as heat transfer fluids in the semiconductor industry, where they are used for temperature control of manufacturing equipment while reducing a facility's greenhouse gas emissions.

3M™ Novec™ Aerosols
3M™ Novec™ Electronic Degreaser, Flux Remover, Contact Cleaner Plus and Contact Cleaner/Lubricant are formulated with 3M™ Novec™ 7200 Engineered Fluid – a solvent uniquely positioned to achieve compliance with California Air Resources Board (CARB) regulations.
All 3M™ Novec™ Aerosol Products are RoHS/WEEE compliant. RoHS, which stands for the Restriction of Hazardous Substances Directive, bans the sale within the EU of new electronic and electrical equipment containing more than the agreed-upon levels of six hazardous substances: Lead; Mercury; Cadmium; Hexavalent Chromium; and two flame retardants used in plastics: Polybrominated Biphenyls and Polybrominated Diphenyl Ether. WEEE, or Waste Electrical and Electronic Equipment Directive, is designed to reduce toxic e-waste by setting collection, recycling and recovery targets for electrical equipment.
3M™ Novec™ Contact Cleaner can be used in compliance with the U.S. EPA's Aerospace NESHAP (National Emissions Standards for Hazardous Air Pollutants). The Novec aerosol product line also includes several azeotropes with improved cleaning strength. These products provide an excellent balance of safety, performance and environmental properties, and as such are valuable and allowable options for both hand wipe and flush cleaning in aerospace facilities. However, because they are formulated with HFE solvents and solvents that are VOCs, two Novec aerosol cleaners, Novec Flux Remover and Novec Electronic Degreaser, are classified as "Option 2" solvents under the Aerospace NESHAP. Option 2 solvents are allowable, but must be used in conformance with specific housekeeping and recordkeeping procedures.

3M™ Novec™ Electronic Surfactants
3MT™ Novec™ 4200 is in full compliance with the chemical regulations of TSCA under Low Volume Exemption and has been approved for buffered oxide etch, quartz crystal etch operations for electronics fabrication and as a rinse additive for semiconductor manufacture. Consult the MSDS for additional information.
All components of 3M™ Novec™ 4300 Electronic Surfactant are fully compliant with the chemical regulations of TSCA. Novec 4300 surfactant contains a PFBS-based fluorosurfactant that was notified to the US EPA under a low volume exemption (LVE). The use of Novec 4300 as a surfactant in semiconductor fabrication and microelectronics processing is allowed. Proper exposure control can be managed by use of personal protective equipment (PPE) as suggested in the Material Safety Data Sheet (MSDS).
PFBS-based surfactants are not included in the U.S. EPA's PFAS Final Significant New Use Rule (Perfluoroalkyl Sulfonates; Significant New Use Rule, 67 Fed. Reg. 72, 854, Dec. 9, 2002) or the US EPA LCPFC (Long Chain Perfluorinated Chemicals) Action Plan.

3M™ Novec™ 1230 Fire Protection Fluids
From its initial development, 3M™ Novec™ 1230 Fire Protection Fluid was designed to address the global demand for a halon or CO2 replacement that is safe, effective and not subject to current or anticipated regulatory restrictions, nor scheduled or targeted for future phaseout. With zero ozone depletion potential, short atmospheric lifetime and a global warming potential of 1, Novec 1230 fluid has proven to be the first chemical clean agent halon replacement to offer a viable, long-term, sustainable solution.
In recent years, growing concerns about climate change have led to increasing regulatory scrutiny of first-generation clean agents that have high global warming potentials. These so-called "greenhouse gases" include several conventional halon replacements, such as HFCs.
Under the Kyoto Protocol and other international agreements, more and more industrialized nations have committed to reducing the amount of greenhouse gases emitted to the atmosphere. Although the use of HFCs in applications such as fire protection and heat transfer is allowed today, there is growing concern about their future viability, as regulators look for industries and applications where alternatives exist to reduce greenhouse gas emissions, without harming economic growth. Ultimately, a growing number of end-users are concluding that long-term economics – as well as good stewardship – favor the use of sustainable technologies, such as Novec 1230 Fire Protection Fluid.
