Fumed silica thickening of epoxy resins - Pro tips

Fumed silica for the thickening and thixotropy of hardeners for epoxy resins. By adding fumed silica to the less viscous hardener component, blending mistakes can be avoided and a more homogenous mixture obtained. Note that fillers can be suspended in the hardener component with the proper choice and use of AEROSIL® fumed silica.
