Application

1. In the organic silicones, it is used as the catalyst of Dimethyl silicone oil, benzyl methyl silicon oil, organic silicon diffusion pump oil, solvent-free silicon molding plastics, silicon rubber for organic silicone resin.


Use Tetramethylammonium hydroxide as catalyst, the advantage is when heating after reaction, it can be decomposed into gas, this gas doesn’t remain in the product.

2.   In the analysis, it is used as polarographic reagent.

3. In the product's purification, it is used as ash-free alkali for precipitating lots of metal elements.

4. It is usually used as brightener cleaner and touch cutting agent for computer silicon wafer surface during the production of silicon wafer.

Package

250/Plastic bottle, 40bottles/Package, or as customer's requirement.
