Application

TMAH-25 (Tetramethylammonium hydroxide aqueous solution) is a versatile chemical solution that serves a wide range of purposes across different industries due to its unique properties. In the organic silicon sector, it acts as a catalyst in the production of materials such as dimethyl silicone oil, organic silicon resin, and silicon rubber, providing the added benefit of being easily removable without polluting the end products. TMAH-25 also finds applications in chemical analysis, particularly in polarography experiments where it functions as a polarographic reagent. In the field of thermochemolysis for studying fungal degradation of wood, it serves as an essential analytical reagent. During chemical purification processes, TMAH-25 is employed to facilitate the removal of metal elements as an ash-free alkali and source of base, aiding in the precipitation of these elements. In the electronics industry, it plays a critical role in the production of computer silicon chips, functioning as a brightening agent, anisotropic etching agent, cleaning agent, and photoresist developer. Furthermore, it is a valuable cleaning agent in the printing of circuit boards and acts as a chemical stripper in semiconductor manufacturing. In the synthesis of ferrofluids, TMAH-25 is utilized as a surfactant to inhibit nanoparticle aggregation, while in the synthesis of zeolites, it serves as a structure-directing agent governing acid-base and redox reactions.
