116821-45-5 - Introduction
11-Aminoundecyltriethoxysilane is an organosilicon compound, often abbreviated as A- 1130. The following is a description of the nature, use, preparation and safety information of the A- 1130:
Nature:
-Appearance: Colorless to light yellow liquid
-Molecular formula: C23H58NOSi
-Molecular weight: 414.88g/mol
-Melting point:-72 ℃
-Boiling point: 230-240 ℃
-Density: 0.881g/cm3
-Solubility: Soluble in organic solvents, insoluble in water
-Stability: relatively stable to acid and alkali
Use:
- A- 1130 is widely used in coatings, adhesives and sealants and other industrial fields. It can be used as additives such as toughening agent, adhesion agent and anti-moisture agent to improve the wear resistance, adhesion and water resistance of the coating.
-In building materials, A- 1130 can be used as a modifier to improve the adhesion, water resistance and weather resistance of materials such as cement, gypsum and concrete.
-Because its molecular structure contains amino and ethoxy functional groups, A- 1130 can also be used as surfactants, emulsifiers and dispersants.
Preparation Method:
- A- 1130 is obtained by reacting undecylammonium bromide with 3-aminotriethoxysilane. First, undecylammonium bromide is reacted with 3-aminotriethoxysilane under appropriate conditions and purified by distillation to obtain a pure product.
Safety Information:
- A- 1130 is a low-toxic compound under routine use conditions, but it is still necessary to pay attention to safe operation and avoid contact with skin and eyes.
-During use, good ventilation conditions should be maintained to avoid inhalation of its vapor. Immediately after contact, rinse with plenty of water and seek medical help.
-When storing, the A- 1130 should be sealed and stored in a dry, cool place, away from fire and oxidizing agents.
