Product Data
Properties Designation
  • Varying surface areas (200-550m²/g)
  • Particle sizes (5-14nm)
  • Stabilising ions (Na, NHȝ, K, Li)
  • High and low pH variants

The trade name of our colloidal silica contains two pairs of digits to represent the basic properties of the materials:

  • The first pair gives the average particle diameter (in nm).
  • The second pair gives the solids content in mass%.
  • Letters in the name refer to special modifications (e.g. Na for sodium stabilised).
Application Areas
Application Functions Product
Adhesives Functional fillers & binders for adjusting viscosity, increasing thermal stability & mechanical strength of bonded joints. GEO40™ SOL-1440Na
Construction Stabiliser and sedimentation reducer in high performance concrete. Concrete surface modification (Finishing). Where ground consolidation is required. Cementing in oilfield drilling, securing of drill holes. Shotcrete additive and improved control of the flow behaviour of concrete sludge. GEO40™ SOL-0830Na GEO40™ SOL-1030Na
Electricity Storage & Electromobility Gel & AGM Accumulators Generation of solid electrolytes for acid-based systems. GEO40™ SOL-1440Na
