LUDOX^® CL is an acidic 30% aqueous dispersion of surface-treated colloidal silica. This LUDOX^® grade carries a positive surface charge and is used as a surface modifier for paper.

LUDOX^® CL-P is an acidic aqueous dispersion of surface-treated silica. It carries a positive surface charge and is typically used as a frictionizing aid for paper.

LUDOX^® DF is an aqueous dispersion of silica with a 12 nm particle size. It is designed to be used in floor coatings to increase friction and reduce slip.

LUDOX^® TM-50 is a dispersion of anionic silica with an average particle size of 22 nm. It is often used as a surface-modifying agent in paper and textile coatings.

LUDOX^® TMA is an anionic colloidal silica designed to be stable over a broad pH range. It is used to prepare ethyl silicate–silica hybrid binders that create slurries used in casting.
