Rheology Control

With HDK® pyrogenic silica, liquid coating formulations retain an optimum rheology profile throughout their product life cycle. During storage, settling is prevented while, in the application phase, leveling and sagging behavior are perfectly balanced.

How the three-dimensional HDK® network works


  • Rheology control
  • Antisettling effects
  • Enhanced free flow in powder coatings


  • Anticorrosive coatings
  • Wood coatings
  • Automotive coatings
  • Coil coatings
  • Heat-resistant coatings
  • Marine and protective coatings
  • Strippable coatings
  • Windturbine coatings
  • Plastic coatings
