Strategies for (TMAH) Recovery and Recycling

SACHEM has developed a closed loop recovery and recycling system for TMAH.  It helps in the safe handling of TMAH by limiting exposure.

Industrial Uses

One of the industrial uses of TMAH is for the anisotropic etching of silicon.[10] It is used as a basic solvent in the development of acidic photoresist in the photolithography process, and is highly effective in stripping photoresist. TMAH has some phase transfer catalyst properties, and is used as a surfactant in the synthesis of ferrofluid, to inhibit nanoparticle aggregation.

TMAH is the most common reagent currently used in thermochemolysis, an analytical technique involving both pyrolysis and chemical derivatization of the analyte.*
