LUDOX® AM is an aqueous dispersion of colloidal silica typically used as a binder in coating formulations. It is designed to have broader pH stability.
LUDOX® AM is a 30% aqueous dispersion of colloidal silica with a particle size of 12 nm. It is formulated to give broader pH stability than standard alkali stabilized grades. LUDOX®AM can be incorporated at neutral to slightly acidic pH to yield a stable formulation. It also has excellent binding strength. For these reasons LUDOX™ AM is used as a binding additive in coatings and adhesive formulations to improve durability and cohesive strength.
