Novec™ 649/1230 (FK-5-1-12) are trademarked brand names for the line of electronics coolant liquids and fire protection fluid sold commercially by 3M. It is also known as “waterless water” or “dry water”. FK-5-1-12 is a fluorinated ketone with the systematic name 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone and the structural formula CF3CF2C(=O)CF(CF3)2, a fully-fluorinated analog of ethyl isopropyl ketone.
3M produces FK-5-1-12 under different brand names of Novec 1230 and Novec 649. These two products have different purity grades (>99% and >99.9%, respectively) intended for different industrial applications.
Novec 1230 is used as gaseous fire suppression agent in scenarios where water-based fire suppression (for example, from a fire sprinkler) would be impractical or where it could damage expensive equipment or property, such as museums, server rooms, banks, clean rooms and hospitals. It functions by rapidly removing heat to extinguish a fire before it starts. It can be used in both total/partial/localized flooding systems, and directional spray type applications; it is also used in portable extinguishers for specialized applications. The Patent for Novec 1230 as fire extinguishant has ended on July 19, 2020.
Recently, it has found active use in microencapsulated form   in the manufacture of fire-extinguishing composite materials. Samsung SDI is using them to extinguish fires in the early stages of modular high-capacity storage systems (ESS) based on lithium-ion batteries for solar panels and electric vehicles. So in August 2019, Samsung SDI officially announces an investment of $ 169 million in a fire extinguishing system in the form of fire-extinguishing composite materials based on microencapsulated Novec 1230. Later reports on the successful passage of the UL9540A test.
Novec 649 is a low temperature heat transfer fluid. It has been used as a full-immersion fluid in a proof of concept data center cooling system by Intel and SGI. As it boils off easily due to its 49 °C (120.2 °F) boiling point, it is used in two-phase immersion cooling system with a condensing loop running cold water. Effects of evaporative cooling was utilized to remove additional heat. Novec 649 is also being considered to be used for cooling silicon photomultiplier (SiPM) sensors to −40 °C (−40 °F) in single-phase configuration as part of Large Hadron Collider’s high luminosity upgrade.
Traditional Perfluorocarbons (PFCs) based compounds for cooling such as Fluorinert™ has extremely high Global Warming Potential (GWP) of over 9,000. Novec 649 was chosen instead as good drop-in replacement due to having similar thermo-physical properties to Fluorinert FC-72 (perfluorohexane, C6F14) while having very low global warming potential (GWP) of 1.
Novec 649/1230 does not deplete ozone (ODP 0) and has a global warming potential of 1 (over 100 years), equivalent to that of carbon dioxide. The Globally Harmonized System of Classification and Labeling of Chemicals (GHS) classifies this chemical as H412 - Harmful to aquatic life with long lasting effects. Photolysis in sunlight, hydrolysis and hydration may be a significant sink of Novec 649/1230 in the environment. It has very short estimated atmospheric lifetime of around five days.
