The Chemistry of Colloidal Silica

The mission of a densifier is adding silica to the surface of concrete. Lythic Densifier with Reactive Colloidal Silica is 99.5% pure silica, suspended by charge repulsion in an ultra-low surface tension liquid by a proprietary, “green” manufacturing process. It increases the density of the concrete surface, making it less permeable to liquids.

Functionality for Levasil Colloidal Silica

Colloidal silica makes surfaces more hydrophilic, causing more moisture to be retained by surfaces during drying, which reduces their tackiness. Considered small “glass particles,” colloidal silica resists high temperatures (SiO2 has a melting point of about 1650ºC) and even under high temperature particles stay discrete and do not fuse.
