| 1 | A water repellent treatment agent for powder | Hydrophobic treatment and performance reinforcement of powder: Diatomite, Silica, Titanium, etc. | As an silicone monomer, it is an intermediate of silicone as the initial raw material. It is widely used in silicone rubber, silicone oil and other deep processing products. DVTMDZ can improve the strength and hardness of fumed silica in silicone rubber. | High |
| 2 | Viscous agent | Bonding agent used as a photoetcher in the semiconductor industry | It is used as silane coupling agent. And it needs to meet the requirements of photoetcher in organic silicone modified resin system of | Low |
| 3 | Pre-polymer material | Used to prepare polysilazane. And it is the original material of ceramic precursor polymer or modifier | No data | Low |
| 4 | Preparation of pharmaceutical intermediates | Medicine | To realize the silylation treatment, hexamethyldisilazane is currently applied in mature and large quantities | Low |
Product package
Plastic lining steel drum, net weight 15kg&160kg
Reaction Character
In the presence of a catalyst, it reacts with alcohols or phenols to produce ethyldimethylalkoxylsilane or ethyldimethylaroxysilane. And react with anhydrous hydrogen chloride to release NH3 or NH4Cl to form ethyldimethyl chlorosilane. It can be prepared by reacting ethyl dimethyl chlorosilane with NH3. It is used as a surface hydrophobic treatment agent for silica in gas phase process and as a reagent to provide N atoms in organic synthesis reactions.
