AEROSIL® R 7200 is a structure-modified fumed silica aftertreated with methacrylsilane to ensure high filler loading.

Scope of Application

Properties Low thickening effect Possible to incorporate up to 20 weight-% using the usual dispersion technology (such as bead mill) Acts as an active filler in acrylate systems As a filler it can increase the scratch resistance of paint and coating systems (such as UV-curing) and printing inks As a filler it improves the mechanical properties, such as the hardness of plastics Applications Methacrylate-functionalized reinforcing additive with cross-linking option for polymers, composite materials, printing inks, and acrylate-based coatings To improve the mechanical stability of acrylate systems, such as resistance to abrasion or scratches
