LUDOX® Grade Selector Guide

LUDOX® AM is a colloidal silica modified to be stable over a wide pH range. It is used primarily as a binder, surface modifier, and flocculant.

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® CL-X is an aqueous dispersion of monodisperse amorphous silica particles that are 22 nanometers. It is used to increase the coefficient of friction on paper, linerboard, and corrugated sheets.

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® HS-40 is an alkaline colloidal silica that offers a good balance between high binding strength and stability in coating and refractory applications.

LUDOX® SM is an amorphous colloidal silica with a particle size of 7 nm. It is a highly temperature-stable binder used in coatings and refractories and as a pozzolanic additive for concrete densifiers.

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.
