Making a good connection
Binding is the process of drawing and holding together materials to form a cohesive whole. Colloidal silica is the perfect binder in a number of different binding applications:
- 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).
- At lower temperatures, colloidal silica can form an inorganic matrix based on chemical bonds (zinc-rich primers and cementitious systems).
- 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.
Colloidal silica benefits
- Increased temperature tolerance
- Chemically inert
- Easy to use
- Safe handling
