天津Silane coupling agent ND-63

Chemical name: Phenyltrimethoxysilane

CAS number: 2996-92-1

Appearance: Colorless transparent liquid, soluble in various organic solvents.

Boiling point: 233 ° C

Density( ρ 20) G/cm3: 1.062 ± 0.005

Refractive index (n25D): 1.468 ± 0.005

Purpose:

1.Used as a raw material for the preparation of polymer organosilicon compounds.

2. It can be used as a crosslinking agent for silicone resin and as a raw material for phenyl silicone oil and silicone rubber. Phenyltrimethoxysilane is a single molecule chemical substance that reacts with water to form silanols and methanol. After hydrolysis, reactive silanols are formed, which can condense with other silanol groups (such as silanol groups on the surface of silica fillers) to form siloxane chains.

3. Siloxane condensation products can form stably on other oxides such as aluminum, zirconium, tin, titanium, and nickel, but are relatively stable with oxides of boron, iron, and carbon, and cannot form on the surface of alkali metal oxides and carbonates. The moisture in the air or on the surface of the substrate may be sufficient to ensure hydrolysis, but in some cases, it may also be necessary to add water to increase the degree of hydrolysis.
