Use:
1. Amino and ethoxy groups are used to couple organic polymers and inorganic fillers, respectively, to enhance their adhesion, and to improve the mechanical, electrical, water resistance, aging resistance and other properties of the product. Applied to mineral-filled thermoplastic and thermosetting resins such as phenolic, polyester, epoxy, PBT, polyamide, carbonate, etc., which can greatly improve the physical and mechanical properties of dry and wet bending strength, compressive strength and shear strength of reinforced plastics Performance and wet electrical properties, and improve the wetting and dispersibility of fillers in polymers. In resin sand casting, the adhesion of resin silicon sand is enhanced, and the strength and moisture resistance of molding sand are improved. In the production of glass fiber cotton and mineral wool, adding it to the phenolic binder can improve moisture resistance and increase compression resilience.
2. Excellent adhesion promoter, can be used for polyurethane, epoxy, nitrile, phenolic adhesives and sealing materials, improve the dispersion of the pigment and improve the adhesion to glass, aluminum, iron metal, also suitable for polyurethane, ring Oxygen and acrylic latex paint.
3. Used in the synthesis of amino silicone oil and its emulsion.
Packaging and storage:
1. Plastic barrel packaging, special specifications need to be reserved.
2. The product should be sealed and stored in a cool and ventilated place.
