3-Aminopropyltrimethoxysilane
APS is a new reactive silane coupling agent, which is prone to hydrolysis and cross-linking reaction. In addition, APS is widely used as reinforcing agent and cross-linking promoter in composite materials, coatings, inks, glues and sealing materials, as well as resin modified additives and enzyme fixative.

Amino and methoxy groups are used to couple organic polymers and inorganic fillers, enhance their adhesion, and improve their mechanical, electrical, water and anti-aging properties. The thermoplastic and thermosetting resins, such as phenolic, polyester, epoxy, PBT, polyamide and carbonate, which are used in mineral filling, can greatly improve the physical and mechanical properties, such as dry and wet bending strength, compressive strength, shear strength and wet electrical properties of the reinforced plastics, and improve the wettability and dispersion of the fillers in the polymer. In resin sand casting, the adhesion of resin silica sand is enhanced, and the strength and moisture resistance of molding sand are improved. In the production of glass fiber cotton and mineral cotton, adding them to phenolic binder can improve moisture resistance and increase compression resilience.

It is an excellent adhesion promoter, which can be used in polyurethane, epoxy, nitrile, phenolic adhesives and sealing materials, improve the dispersion of pigments and improve the adhesion to glass, aluminum and iron metals, and also suitable for polyurethane, epoxy and acrylic latex coatings. At the same time, it can also be used for the synthesis of amino silicone oil and its emulsion.

3-Chloropropylmethyldimethoxysilane
It is a kind of intermediate with a wide range of uses. It can be used to prepare a variety of coupling agents and special silicone oil
