| Technology Advantages |
| TMAH (VLSI)is widely used in electronic industry ,especially as positive photeresist developer in LCD& VLSI , silicon wafer wet etchant and super clean solution for CMP process. TMAH (VLSI) aqueous is divided into 25% ,20%and 2.38% solution , in which the metal lower than 10 ppb through ICP detection , conform to the international general criterion ,and quality can be compared with same products of famous company ,such as SHOWA,SACHEM SHOW,TAMA and MERCK.
TMAH (industrial grade ) is widely Used as an effective phase transfer catalyst during organic silicon polymerization in rubber industry. The quality of greenda¡¯s TMAH (industrial grade ) is closely to that of electronic grade, but price is only near the level of other company¡¯s industrial TMAH. So it is very competitive and popular with the customers.
