Property

It can absorb CO2 in the air rapidly, it forms carbonate which is organic strong Alkali with strong corrosivity, it will be hygroscopic when exposure to air for long time, so it should store with good seal, decomposition temperature is 135 ° C.

Specification

Appearance: White needle-like or crystalline powder

Assay:  98%min

Carbonate:0.5%max

Non-volatile matter:0.1%max

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:250g/bottle, 10kg/ carton.
