  • Efficient effect as flow agent in very different applications, such as powder coatings, toners, or cosmetics
  • Enhances the anti-corrosion properties for coatings
  • To improve the storage stability of oil dispersions in agrochemicals
  • Improves the mechanical properties of various polymer systems, such as silicone rubber
