Features and uses :

  1. Amino groups and ethoxy groups are used to couple organic polymers and inorganic fillers to enhance their cohesiveness and improve the mechanical, electrical, water resistance, and anti-aging properties of the product. PBT, polyamide, carbonate and other thermoplastics applied to mineral filling can greatly improve the physical and mechanical properties of reinforced plasticssuch as wet and dry flexural strength, compressive strength, shear strength and wet electrical properties, and improve the filler in Wettability and dispersibility in polymers.
  2. Excellent adhesion promoter, can be used in nitriles, adhesivesand sealing materials, improve the dispersion of pigments and improve the adhesion to glass, aluminum, iron metal, and also suitable for acrylic latex paint.
  3. In resin sand casting, it can enhance the adhesion of resin silica sand, improve the strength and moisture resistance of molding sand.
  4. In the production of glass fiber cotton and mineral wool, adding it to the phenolic binder can improve moisture resistance and increase compression resilience.
  5. Used in the synthesis of amino silicone oil and its emulsion
  6. In the manufacture of grinding wheels, it helps to improve the adhesion and water resistance of the phenolic resin adhesive of wear-resistant self-setting sand.

Packaging and storage :
1. Packed in plastic drum, net weight 25 kg or 200 kg per drum.
2. This product should be airtight and stored in a cool and ventilated place.
