High Purity Peg Price - Supplier Industrial/Electronic Grade TMAH 25% Tetramethylammonium Hydroxide – Zhuoer Detail:

Tetramethylammonium hydroxide (TMAH or TMAOH) is a quaternary ammonium salt with the molecular formula [(CH3)4N]+[OH]-, and is the simplest member of the class of organic quaternary ammonium compounds. One of its industrial uses is for the anisotropic etching of silicon. It is also used as a basic solvent in the development of acidic photoresist in the photolithography process. Since it is a phase transfer catalyst, it is highly effective in stripping photoresist. It is also used as a surfactant in the synthesis of ferrofluid, to prevent agglomeration.
