Zircar Refractory Composites SILICA RIGIDIZER HARDENER SI-HARD
Subcategory: Oxide, Silicon; Oxide
Material Notes: ZRCI SI-HARD Rigidizer Hardener is a alkaline, aqueous dispersion of colloidal silica at 50% concentration. The dispersed silica is present as amorphous spheres, 100 nanometers in size. The silica present is non-agglomerated and is completely dispersed. There is no mixing or dilution required. The particles carry a slightly negative charge and have a large surface-to-weight ratio. It is used for rigidizing and hardening the surfaces of ZIRCAR ceramic textile, papers and blankets. It also is ideal as a coating agent and binder.Information provided by ZIRCAR Refractory Composites, Inc. (ZRCI)
