Overview
LUDOX® AM-FS is a 28% aqueous dispersion of colloidal silica with a particle size of 12 nm. LUDOX® AM-FS particles have a very high surface area. The surface of these particles is rich in silanol groups, which makes it a highly reactive binder of metals, ceramics, and other inorganic materials. It is formulated to give broader pH stability than standard alkali-stabilized grades and can be incorporated into solutions with neutral to slightly acidic pH and yield a stable formulation. Because of its freeze-thaw stability, LUDOX® AM-FS is recommended for use in formulations or operations that exist in below-freezing temperatures.

Applications
LUDOX® AM-FS is useful as an additive in functional coatings and adhesives as a reinforcing agent, binder, and surface modifier. It can also promote the adhesion of coatings and adhesives onto inorganic materials, such as metal and glass, where durability and abrasion resistance is also increased. The freeze stability of LUDOX® AM-FS makes it ideal as a raw material source of silica or in concrete-densifier formulations that are applied in below-freezing temperatures. LUDOX® AM-FS is also preferred in ceramic applications where silica is needed as a binder to improve cohesive strength.
