LUDOX® SM contains synthetic colloidal silica with a particle size of 7 nm. It is a highly temperature stable binder used in coatings and refractories.
LUDOX® SM is an aqueous dispersion containing 30% synthetic amorphous silica with a particle size of 7 nanometers. It features one of the smallest particle sizes of the LUDOX® range and as such is an excellent binder. LUDOX® SM is ideal for applications like ceramic manufacturing and casting that require a binder that is stable in high temperatures. It can also be used to improve durability of coating formulations by increasing cohesive strength. LUDOX® SM binds well to metal and as such can be used as an adhesion promoter and reinforcing agent for caulks and sealants.
