Physical Form
Product Properties
  • Hydrophobic component for thickening and reinforcement of RTV-1 pack silicone sealants
  • Improves shelf-life of silicone sealants
  • Water resistant, for thickening and hydrophobising of liquid systems
  • Rheology control of (complex) liquid systems
  • For use in coatings as anti-settling agent, for pigment stabilization and improvement of corrosion protection
  • Improves hydrophobicity and rheology of offset printing inks
  • Improvement and maintenance of free flow and anti- caking characteristics of powders
  • Due to large surface area improved thickening and thixotropic effect as well as transparency
