AEROSIL® fumed silica for adhesives and sealants

Thanks to the development of special hydrophobic AEROSIL^® fumed silica, it has been possible to produce structural adhesives that belong to the future technologies in automobile construction. Modern structural adhesives enable the joining of various materials, such as steel, aluminum, magnesium, and plastics. The use of new processes, such as weld bonding, which combines the individual advantages of gluing and spot welding, makes it possible to improve the mechanical strength of the automobile body (chassis), especially for improving the crash safety and sound dampening.

Furthermore, structural adhesives have made it possible to construct lightweight design components, such as bonded roof modules.

Numerous systems can benefit from the technical advantages and improvements that may be achieved with Evonik's large selection of AEROSIL^® grades, which have been specially developed for the adhesives and sealants industry. These special AEROSIL^® grades not only improve the rheological and mechanical properties, but also act as anti-settling agents, and improve the storage stability and processability of adhesives and sealants.
