Advantages
  • good flowability, dispersion properties
  • good emulsion & suspension stability
  • modified pay-off in stick applications
  • shows improved sweat resistance in long-wearing make-up products
  • provides temperature, mechanical & storage stability
  • converts water or dilute aqueous solutions to a dry powder
  • effective rheology control in complex liquid systems (such as 2 K PUR coatings)
  • can be applied in coatings systems as an anti-settling agent, for the stabilization of pigments and to enhance the effect of corrosion protection
  • Free flow aid in powder coatings
  • can easily be incorporated into silicone rubber formulations and improves their mechanical and optical properties
