Functions and Uses：
1. It is the type of acid organotin process and is the pure tin plating with less foam generation. In the medium and high-speed plating conditions, HMM can produce the tin deposit with matte and semi-bright appearance.
2. In terms of a wild operating parameter comprising the current density, stirring, or others, HMM all can assure the high stable deposition.
3. Through neutralizing by water washing, the tin salt can all precipitate, which is an important improvement over the fluoroborate system.
