Main Uses

  Amino and ethoxy groups are used to couple organic polymers and inorganic fillers respectively to enhance their cohesiveness and improve the mechanical, electrical, water resistance and anti-aging properties of products. Thermoplastic and thermosetting resins such as phenolic, polyester, epoxy, PBT, polyamide and carbonate used in mineral filling can greatly 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 dispersion of fillers in polymers.In resin sand casting, the adhesion of resin silica sand is strengthened, the strength and moisture resistance of moulding sand are improved. In the production of glass fiber cotton and mineral cotton, the moisture resistance and compression resilience can be improved by adding it to phenolic binder.

  Excellent adhesion promoters can be used in polyurethane, epoxy, nitrile, phenolic adhesives and sealants, improve the dispersion of pigments and improve the adhesion of glass, aluminium and iron metals. They are also suitable for polyurethane, epoxy and acrylic latex coatings. They are widely used in plastic coupling agents, paint coupling agents and glass paint coupling agents.

  It is used for the synthesis of amino silicone oil and its emulsion.
