On May 19, 2026, an in-depth analysis on the application of Wacker HDK® fumed silica in adhesives and sealants was officially released. SFEP, as an authorized distributor of Wacker in China, comprehensively interpreted its core value and application solutionsWacker Chemie AG. With nano-scale particle size and three-dimensional network construction capability, fumed silica serves as a key material for adhesive rheology control. It realizes thickening, shear thinning and thixotropic recovery through reversible hydrogen bonding, effectively improving viscosity stability, sag resistance and reinforcement effectWacker Chemie AG. This analysis covers the full range of hydrophilic and hydrophobic grades, providing precise selection for low-polarity and high-polarity systems, adapting to epoxy, polyurethane, silane-terminated polyether adhesives, chemical anchors and other scenarios, with clear dosage and dispersion specificationsWacker Chemie AG. New models such as HDK® H21 and H2000 feature high hydrophobicity, easy dispersion and high strength, meeting the needs of high-end industrial adhesives and boosting quality and efficiency in electronics, automotive, construction and other fieldsWacker Chemie AG. SFEP provides one-stop services including product supply, selection guidance and process optimization, promoting the high-performance and refined development of the adhesive industryWacker Chemie AG.
