Flexisil™ 14-40 NH4
Innovative Chemical Technologies Inc. · Flexisil™
Flexisil™ 14-40 NH4 is an ammonia-stabilized, aqueous nanoparticle dispersion of amorphous colloidal silica. The silica particles are discrete, slightly rough, and spherical in shape. This sol is processed to be a very low sodium product, making it suitable for applications such as inorganic binders, catalysts, coatings, and vacuum-formed refractory shapes.
- Low sodium content
- Suitable for refractory applications
- High surface area
- Versatile applications
