Hydrophobic silica, created through surface modification of hydrophilic fumed or precipitated silica, is a high-performance additive with critical roles in paints, adhesives, sealants, personal care, and the pharmaceutical sector. In 2025, production of hydrophobic silica is anticipated to rise steadily, growing at 4–6% annually, supported by increased demand for moisture-resistant, anti-caking, and rheology-control agents. Asia-Pacific is leading global production thanks to strong demand from industrial coatings, while Europe maintains a significant share due to advanced manufacturing technologies and quality standards.
