Despite the fact that 3M Novec 1230 decomposes quickly in the atmosphere (0.014 years), as part of its use as an ecologically clean fire protection agent, it is required that the given compound should have chemical stability and stay unchanged during the entire period of operation of the fire protection system. It is essential to examine a number of factors for the potential effects on the suppression compound in the procedure of processing, storage and usage in the fire protection system.

The systems installed on the sites of commercial aviation, trading ships and military sites, as estimated, must serve more than 30 years. It is essential that the agent which is contained in these systems, should keep its chemical composition during this entire period for the purpose of effective use of a clean fire protection compound at the moment of actuation of the fire protection system. For any alternative Fire Protection Fluid, it is essential to place similar requirements. From the date of production of Novec 1230 in commercial use, there are still no other samples of the compound with the age of more than 10 years.

Stability parameters of 3M Novec 1230


However, accelerated aging of the agent has been conducted, which predicts the condition of the compound during a much longer period of time. For example, 3M Novec 1230 was stored at 100°C temperature for more than 1500 hours in the presence of metal samples, used for production of modules of the type MPA-NVC 1230 (6061-T6 aluminium; C26000 brass; UNS 10100 copper; ASTM A 516, Gr. 70 from carbon steel, and Types AISI 304L and 316L from stainless steel). Based on the van' t Hoff principle, it simulates more than 30 years of aging at room temperature.

After 1514 hours of heat aging of Novec 1230, the metal samples were taken out and visually examined. Certain examples were analysed with SEM Scanning Electron Microscopy and EDS. On the samples from carbon steel, aluminium, brass and copper only extremely weak surface deposits were observed which were caused by a high content of fluorine.

The sample from stainless steel did not show any significant surface deposits. Neither of the analysed samples were corrosive.

The results of the research were published in the laboratory report № L-1954A by Engle Metallurgical, Ltd.

The cleanliness of Novec 1230, before and after heat aging, was analysed with Gas Chromatography–Mass Spectrometry (GC-MS), as well as fluorine and Proton Nuclear Magnetic Resonance (Proton NMR). Heat aging of samples of Novec 1230 lead to minor changes of the chemical compound, in accordance with the requirements of minimal cleanliness of an agent, as described in the systems of standards such as NFPA 2001 and ISO 14520.

Based on these results it was concluded that 3M Novec 1230 maintains stability and can be used as a clean fire protection agent during the entire period of operation, including periods of service and activation of the fire protection system.
