LUDOX® Grade Selector Guide

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® 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® HSA is a slightly acidic, deionized colloidal silica with a particle size of 12 nm. It's used as a binder in coatings to improve durability.

LUDOX® PW-50 EC is an alkaline colloidal silica with low specific surface area. It is used as an abrasive in polishing slurries and as a surface modifier.

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

LUDOX® SM contains amorphous colloidal silica with a particle size of 7 nm. It is a highly temperature stable binder used in coatings and refractories.

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

LUDOX® AM is an aqueous dispersion of silica that has been modified to be stable over a wide pH range. It is used primarily as as a binder & flocculant.

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® TMA is an anionic colloidal silica designed to be stable over a broad pH range. It is used to prepare "hybrid" binders for slurries used in casting.

LUDOX® AS-40 is an alkaline, 40% solids aqueous dispersion of colloidal silica with a particle size of 22 nm. It is stabilized with ammonium and used as a high-temperature binder and catalyst in a wide range of industrial applications.

LUDOX® CL-X is an aqueous dispersion of 22 nanometer amorphous silica particles that is used to add friction to paper, linerboard, and corrugated sheets.

Lithium Polysilicate is an aqueous solution of SiO2/Li2O with a high ratio silicate of 4.8. It is commonly used as a concrete hardener.

LUDOX® HS-30 is a colloidal silica with an average particle size of 12 nm particle size. It is used as a binder in casting and ceramics applications.

LUDOX® SM-AS is an ammonium stabilized colloidal silica with 7 nm particle size. It is used as a binder in applications that require extreme temperatures.

LUDOX® AS-30 is an alkaline dispersion of amorphous silica stabilized with Ammonium. It is typically used as a binder in high temperature applications.
