On December 20, 2022, 3M announced the discontinuation of Novec series products by the end of 2025 due to environmental regulations, and the semiconductor refrigeration market is expected to undergo significant changes in the next two to three years. Industry insiders predict that the demand for refrigerators that consume little or no coolant will increase. In addition, currently, manufacturers such as Samsung Electronics and SK Hynix are promoting plans to replace coolant, but the industry believes that the original 3M's market share in the coolant market still has a significant impact on the demand market.

PFAS is a series of synthetic organic fluorides that have been widely used in various industries worldwide, such as chip manufacturing, fire extinguishing agents, paints, waterproofing agents, etc. However, the environmental threats brought by the production and use of PFAS have attracted the attention of environmental organizations and policy makers.

On December 20, 2022, 3M announced that it would discontinue production of 58 types of perfluoroalkyl and perfluoroalkyl substances (PFAS) by the end of 2025, including perfluoroalkyl nitrile (C4F7N, 3M Novec 4710), perfluoroapentanone (C5F10O, 3M Novec 5110), methoxy nine fluorobutane (C4F9OCH3, 3M Novec 7100), and ethyl nine fluoroisobutyl ether (C6H5F9O, 3M Novec 7200), in order to reduce or eliminate them. The impact of PFAS on climate, environment, and ecological health.

The reason why PFAS based solvents are widely used in the field of vapor phase cleaning is because they can suppress the flammability of hydrocarbons and alcohols, and improve cleaning performance. Its toxicity is also much smaller than n-propyl bromide (nPB), which is a low-cost and high-performance solvent believed to have many adverse health effects, including carcinogenicity. In short, PFAS makes precision cleaning processes safer. If you are trying to design a PFAS free cleaning process, special consideration should be given: as alternatives without PFAS are either flammable, water-based, or boil at very low temperatures, phasing out PFAS will require a thorough overhaul of the cleaning process.

For example, flammable solvents cannot be used in standard vapor phase cleaning equipment. Special pressurized explosion-proof facilities are required, and water-based cleaning agents require the addition of a large cleaning production line, such as air spray or online cleaning equipment. These requirements increase the design and validation time involved in the changes.

For users affected by the unstable supply of Novec solvents, Techspray offers a range of alternatives that have the same appearance and performance as Novec solvents. The cleaning effect appraisal test can be skipped as an option. COC can be used to ensure that your highest quality standards are maintained.

 

There are two main types of alternatives to Techspray, PWR-4 series and Precision-V series, to improve performance and reduce costs. We can provide customized formulas to meet the requirements.

PWR-4 solvent is designed to replace nPB, TCE, and Perc, matching and surpassing cleaning performance without safety concerns.

Precision V vapor cleaning solvent is an ideal alternative to 3M Novec solvent and AK-225 based cleaning agents.
