Application of methylsulfonic acid

Methylsulfonic acid is a harsh chemical substance, abbreviated as MSA 70% methylsulfonic acid is mainly used in the electroplating field, resin catalysts, and electronic cleaning agents. It has a wide range of application prospects in the electroplating field and has been proven to be a good substitute for fluoroboric acid or phenolic sulfonic acid. Methylsulfonic acid electroplating solution is widely used in tin and tin lead alloy electroplating. The methylsulfonic acid type bright pure tin electroplating has fine and uniform coating crystallization, a bright silver white color, good weldability, and is suitable for the high-end electronics industry, The plating solution has a high electroplating speed, a wide current density range, a fast deposition speed, and excellent deep plating ability. After standard aging tests or long-term storage, it can still maintain good welding performance, does not contain fluoroboric acid, is easy to treat wastewater, has low corrosiveness, and is conducive to environmental protection 99% methylsulfonic acid is mainly used in the production of pharmaceutical antibiotic intermediates
