Fumed silica is used as a thickening agent, anti-precipitating agent, or abrasive depending on the product characteristics, and strengthens and optimizes product properties and functions. OCI started the first fumed silica production in Korea with the KONASIL brand, and has become one of the world’s top fumed silica makers. OCI focuses on high value-added products such as hydrophobic fumed silica, which has a low affinity with water.
