Perfluoro(2-methyl-3-pentanone) is a fluorinated ketone with the structural formula CF3CF2C(=O)CF(CF3)2, a fully-fluorinated analog of ethyl isopropyl ketone. It it used as an electronics coolant liquid and fire protection fluid sold commercially by 3M under brand names such as Novec 1230 and Novec 649. It is also known as “waterless water” or “dry water”. Applications 3M produces perfluoro(2-methyl-3-pentanone) 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 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; also, its density enables it to displace air and thereby deprive the fire of oxygen. Novec 1230 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 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 this product 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. In August 2019, Samsung SDI officially announced its investment of $ 169 million into fire-extinguishing composite materials based on microencapsulated Novec 1230. The firm later reported that UL9540A testing for this product was passed. Novec 649 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 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 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
