1. Thermoplastic and thermosetting resins such as phenolic, polyester, epoxy, PBT, polyamide, and carbonate used for mineral filling can significantly improve the physical and mechanical properties, such as dry wet bending strength, compressive strength, shear strength, and wet electrical properties of reinforced plastics, and improve the wettability and dispersibility of fillers in polymers; 2. Excellent adhesion promoter, can be used for polyurethane, epoxy, nitrile, phenolic adhesives and sealing materials, can improve the dispersion of pigments and enhance the adhesion to glass, aluminum, and iron metals, and is also suitable for polyurethane, epoxy, and acrylic latex coatings; In resin sand casting, this product enhances the adhesion of resin silicon sand, improves the strength and moisture resistance of molding sand; 3. As a representative amino silane with excellent quality, its advantages are more reflected in its excellent water solubility and high purity, which can form stable aqueous solutions. It performs excellently in surface treatment of glass fibers and metal surfaces in aqueous systems; 4. Due to its comprehensive low impurity content, it has demonstrated outstanding performance in various applications in the field of microelectronics.
