Adhesives and sealants
Fumed silica is used as an excellent active reinforcing filler and thickener in the production of liquid adhesives and sealants. It slows the sedimentation, increases the viscosity and gluing capacity and mechanical strength after hardening, reduces the setting time of bonding surfaces.
It is recommended to use fumed silica of the grades FUMISIL175, FUMISIL200, and FUMISIL300. The quantity of the added product is 1-3% of the weight of the material.
