Silane Coupling Agents KH-550:
Aminopropyltriethoxysilane (Formula: C9H23NO3Si, CAS:919-30-2), is a colorless or slightly yellow transparent liquid, soluble in benzene, ethyl acetate, reaction with water. Its applications are as follows:

1. Ethoxy-and coupling were used organic polymer and inorganic filler to strengthen its bond and increase the product's mechanical, electrical, water resistance, anti-aging properties, and so on. Used in the mineral-filled phenolic, polyester, epoxy, PBT, PA, carbonate, such as thermoplastic and thermosetting resins, reinforced plastics can significantly improve the state of wet and dry bending strength, compressive strength, shear strength, and other physical And the mechanical properties of wet electrical performance in polymers and fillers to improve the wetting and dispersion. Resin sand casting, to enhance the bonding resin silica sand, sand to improve strength and moisture resistance. Cotton fiber production in cotton and minerals, to add to the phenolic binder, can increase the moisture and compression to increase flexibility.

2. Excellent bonding agent, can be used in polyurethane, epoxy, Nitriles, phenol-formaldehyde adhesives and sealing materials to improve the color and improve the dispersion of glass, aluminum, ferrous metals adhesion, but also to polyurethane , Epoxy and acrylic latex paint.

3. Used for the synthetic of Amino silicone oil and Emulsion.
