HDK® pyrogenic silica serves as a rheological additive for automotive finishes and refinishes. With a comprehensive range of hydrophilic and hydrophobic grades, there is an optimum solution for every application. The typical HDK® dosage of 0.6 to ~1% allows for very efficient rheological control.

Benefits:

  • PDMS-free
  • Optimal balance of thixotropy and leveling
  • Excellent rheology control in 2K PUR coatings
  • Superior optical transparency
  • Improved anticorrosion performance
  • Superb free-flow agent in powder coatings
  • Improved storage stability

Applications:
