​​Particle Size, Consistency and Purity - Keys to Quality 

LUDOX® colloidal silica products are aqueous dispersions of silica particles in the low nanometer size range that typically exhibit narrow particle size distribution.  Process design and control ensure quality and consistency.  Combined with excellent purity and a wide range of options, these attributes make the LUDOX® colloidal silica family an excellent choice for many applications.

LUDOX® colloidal silica improves the performance of your products as inorganic binders, reinforcing and strengthening agents, refractory bonding agents and sur​face modifiers.  As a binder, it provides excellent strength and adhesion in catalyst washcoats and catalyst structures, precision investment casting molds, insulation boards and other refractory fiber based parts.    It can also be used as a low sodium silica source in the manufacture of zeolites, as co-binders in functional coatings and as flocculating agents in paper manufacture and in beverage clarification.
