Introduction：
With the rapid development of science and technology, the integration of electronic products is getting higher and higher. To ensure the normal function of these products, the cleaning of these products become extremely important. CFC, which was commonly used in the electronics industry in the past, will be banned because it will damage the ozone layer and cause the greenhouse effect. And its substitute HCFC can only be used as a transitional cleaning solvent because it still contains chlorine.
In response to this development trend, Zhejiang Noah Fluorochemical Co., Ltd. has developed a series of hydrofluoroether solvents. Unlike transitional alternative solvents such as HCFC, pcb cleaning solvent Noah®7300 fluid has become a long-term solution due to its excellent environmental protection characteristics. It provides effective, safe, and environmentally friendly solutions for industries that require precision cleaning processes.
pcb cleaning solvent Noah®7300 fluid is a clear, colorless, odorless fluid that has utility in a wide variety of applications, including heat transfer, lubricant deposition, electronic testing and cleaning applications.
Additional Information A nonflammable, segregated hydrofluoroether, pcb cleaning solvent Noah®7300 fluid is low in toxicity, non-ozone depleting and has low global warming potential.
Product Features:
------colorless, odorless, non-toxic, safe and non-flammable, good solubility, insoluble in water, good thermal stability;
------non-ozone depleting, quite low damage to the ozone layer and a very low global warming potential;
------low surface tension, low viscosity;
------Low latent heat of evaporation, excellent material compatibility;
------Good insulation performance, non-conductive, and will not cause damage to electronic equipment
Advantages: Since the performance is closest to CFCs, the formal cleaning equipment can still be used, without increasing equipment investment, and without major changes to the process.
