AERODISP W7520 is an aqueous dispersion of hydrophilic fumed silica. It is a low viscosity, water-based dispersion of AEROSIL fumed silica, with a slightly alkaline pH. AERODISP W7520 offers rheology control, stabilization and surface treatment benefits. As a reinforcing and thickening agent, it improves the mechanical and barrier properties of formulations. It also acts as an anti-settling agent. AERODISP W7520 is ideally suited for applications requiring stabilization of emulsions, reinforcement, viscosity adjustment and anti-blocking properties. It can be used in a variety of coating, adhesive and sealant products for improved performance and extended durability.
