Binding is the process of drawing and holding together materials to form a cohesive whole. Levasil Colloidal Silica is the perfect binder in a number of different binding applications.

Benefits when using Levasil Colloidal Silica

  • Increased temperature tolerance
  • Amorphous and non-crystalline 
  • Easy to use
  • Safe handling


How it works

  1. At high temperatures, colloidal silica particles sinter and bind components together (investment casting, ceramics, and catalyst applications) or form a hard glassy surface coating (electric steel).

  2. At lower temperatures, colloidal silica can form an inorganic matrix based on chemical bonds (zinc-rich primers and cementitious systems).

  3. In a polymer resin based matrix, the surface groups of silane-modified silica particles can react and cross-link with resin groups providing additional binding for the coating system.
