Application Features

Emulsifying properties (halogenated raw materials): Effective
Wetting properties: highly effective
Washing performance: ineffective
Dispersion performance (halogenated raw materials): effective
Foaming performance: effective
Compatibility: Can be widely used in acid/alkali and soft/hard water systems

application
Metal/Electronic: It can improve the etching effect, and can be used as a plating aid and an oxidation inhibitor for zinc batteries; in the flux based on rosin, a fluorosurfactant is added to form a high-efficiency flux (rosin + FC-4430 + glycerin). + isopropyl alcohol), immerse the electronic printed circuit board soldering parts to be soldered in the flux for several minutes. After drying, it can be automatically welded, with good foaming, uniform tinning, full solder joints, and less flux residue. It can improve the strength of the coating and eliminate the common defects such as pinholes and cracks in the electroplating process.
