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^® 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^® 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.
