LUDOX® CL is an acidic, 30% aqueous dispersion of surface treated silica. It carries a positive surface charge and is used as a surface modifier for paper.
LUDOX® CL contains 30% silica with a particle size of 12 nm. The surface of the silica in LUDOX® CL is modified with aluminum in order to induce a positive charge. It is unique in that it is one of the few grades of colloidal silica that has an acidic pH and carries a positive sol charge.

Packaging that slips when stacked.
Telescoping of rolled paper.
Low coefficient of friction on paper surfaces that leads to slipping during storage and transport.
The cationic nature of LUDOX® CL makes it well suited for modifying the surface of paper and other fibrous materials. The friction provided by LUDOX® CL is incredibly useful in packaging applications for anti-slip purposes. LUDOX® CL is also useful as a binder in applications where an acidic pH is necessary in order to retain formulation stability.
LUDOX® Colloidal Silica is used in a wide range of processes to improve the and resiliency of building materials. Formulating LUDOX™ into concrete, coatings, adhesives, and sealants increases productivity and reduces cost while boosting the strength and consistency of the end product.
