LUDOX HS-40 is a synthetic amorphous silica dispersed in a stable form in water. It contains nominal 12 nanometer particle size silica at a concentration of 40% by weight. LUDOX HS-40 provides high binding strength and stability in most applications due to its high silica content and particle size. Its key features include binding strength, stability, and highest silica content for its particle size range. These properties make LUDOX HS-40 well suited for formulations requiring durability, strength and longevity. LUDOX HS-40 is broadly used in industries where its binding properties translate to long lasting performance, such as providing resistance to wear & tear. It can be incorporated in solutions, slurries or dry blends as required.
