AEROSIL® fumed silica for adhesives and sealants

AEROSIL® fumed silica is invented to improve the manufacturing, quality and performance of adhesives and sealants.

Adhesives and sealants

Adhesives and sealants are employed in many different industries and are increasingly finding new applications. Thanks to the development of special hydrophobic AEROSIL® fumed silica grades, it has been possible to produce structural adhesives that belong to the future technologies in the automotive, construction, wind energy and chemical fixing industries.
