3-Aminopropyltrimethoxysilane (CAS No.: 13822-56-5) is an important raw material for the synthesis of amino silicone oil and its emulsion. Its unique chemical structure, including amino (-NH2) and methoxy (-OCH3) functional groups, makes it show excellent reactivity and stability in the synthesis of silicone oil. The following are its key roles and application areas in the synthesis of amino silicone oil:

1. Reactivity and functional properties
Amino functional group: provides reactive sites, easy to react with other compounds (such as epoxy, carboxyl, etc.) to form stable chemical bonds.

Methoxy functional group: after hydrolysis, it generates silanol (Si-OH), which can be further condensed to form siloxane bonds (Si-O-Si), enhancing the stability and durability of silicone oil.

2. Synthesis of amino silicone oil
In the synthesis process of amino silicone oil, 3-aminopropyltrimethoxysilane is used as a key monomer, which is copolymerized with other silane monomers (such as dimethylsiloxane) through hydrolysis and condensation reaction to form silicone oil with amino functional groups. This amino silicone oil has the following properties:

Excellent softness: gives textiles and leather a soft and smooth feel.

Good hydrophilicity: improves the hygroscopicity and antistatic properties of fabrics.

Enhanced adhesion: improves the adhesion and durability of silicone oil on the fiber surface.

3. Application areas
Textile industry: Amino silicone oil is widely used in fabric finishing agents to provide softness, smoothness and anti-wrinkle effects, while enhancing the abrasion resistance and tear resistance of fabrics.

Leather industry: As a leather softener, it improves the softness, gloss and feel of leather.

Cosmetic industry: Used in conditioners and skin care products, it provides lubrication and moisturizing effects, while enhancing the stability and feel of the product.

Industrial field: As a lubricant, defoamer and surface treatment agent, it is widely used in metal processing, plastics and rubber products.

4. Advantages summary
Versatility: 3-aminopropyltrimethoxysilane shows versatility in the synthesis of amino silicone oils, which can meet the needs of different industries.

High efficiency: Its high reactivity and stability ensure the efficient synthesis and excellent performance of amino silicone oil.

Environmental protection: The hydrolysis products are methanol and water, which are environmentally friendly and in line with the development trend of green chemistry.

Amino silicone oil synthesized by 3-aminopropyltrimethoxysilane has become an indispensable functional material in the textile, leather, cosmetics and other industries, providing strong support for product performance improvement and diversified applications.
