3-Aminopropylmethyldiethoxysilane CAS 3179-76-8

Introduction

3-Aminopropylmethyldiethoxysilane is a monoaminosilane, which has an active primary amino functional group and two hydrolyzable alkoxy (ethoxy) groups in its molecular structure. This dual reactivity allows it to improve the bonding, adhesion and compatibility between inorganic materials (glass, metal, filler) and organic polymers (thermosetting resins, plastics, elastomers) through a two-way chemical reaction, thereby improving the mechanical properties of resin-based composite materials or improving the bonding strength and water resistance of resin coatings. In different applications, it can be used as a coupling agent, adhesion promoter, curing agent, surface modifier of pigments and fillers, etc.

Physical indicators

Application 

1. It can be used as an adhesion promoter and tackifier to increase the bonding ability of organic materials to inorganic substrates;
2. It can be used as an important raw material for amino-modified silicone oil and silicone super-soft finishing agent. After coupling the amino group to the silicone oil skeleton, the mechanical and chemical properties of organic compounds are greatly improved;
3. It can be used as an additive in various sealant systems. It can maintain low modulus and improve the mechanical and electrical properties of the final product;
4. It can be used as a surface modifier for inorganic powder and filler treatment.
