Aminosilane oligomers are widely used in many fields due to their excellent performance. Specific uses include:
Coatings, adhesives and sealants industry: Improve the adhesion of amino reactive resins to inorganic surfaces, plastic surfaces and inorganic fillers, reduce system viscosity, improve the dispersibility of pigments and fillers, and improve adhesion and mechanical properties.
Plastic modification: Improve the water resistance, weather resistance and mechanical properties of plastics, and extend the service life of plastic products.
Mineral filler treatment: Produce unique filler functions through diamino and alkyl functional groups, enhance the flexibility, low modulus and high elasticity after curing.
Rubber products: Improve the wear resistance, oil resistance and thermal stability of rubber products, and extend the service life of rubber products.
Biomedical materials: Improve the biocompatibility and durability of materials, improve the mechanical properties of materials, and are suitable for the medical field.
Properties
The main component of aminosilane oligomers is a complex of organic and inorganic substances. The molecular structure contains active amino groups and siloxane segments, which enables it to form strong chemical bonds with materials on different surfaces.
Preparation method
Aminosilane oligomers are usually formed by hydrolysis/condensation of one or more silane coupling agents, and have the characteristics of low volatility, low viscosity, small number of chain links, and high functionality. When this oligomer is used to modify organic polymers, it can significantly improve the thermal stability, impact strength, bonding strength and other properties of the polymer.
In short, aminosilane oligomers have important value in materials science due to their excellent performance and wide application fields. With the continuous advancement of industrial technology, its application prospects will be further expanded.
