AEROSIL R 974 V

Densified hydrophobic fumed silica

AEROSIL R 974 V Is a densified hydrophobic fumed silica aftertreated with DDS (Dimethyldichlorosilane).

Key Features

  • Hydrophobic reinforcing component for HCR silicone rubber
  • Water resistant, 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
  • Improvement and maintenance of free-flow and anti-caking characteristics of powders
  • Improves hydrophobicity and rheology of offset printing Inks
  • Due to large surface area improved thickening and thixotropic effect as well as transparency
  • Improved Incorporation and handling when applying sufficient sheer forces

Recommended Applications

  • Silicone rubber
  • Paints and coatings
  • Negative toner
  • Adhesives
  • Coating polymers
