A colloid, or sol, is a stable dispersion of particles. In other words, the particles are small enough that gravity doesn’t cause them to settle, but large enough not To pass through a membrane, allowing other molecules and ions to pass freely. Particle size ranges from 1-100 nm, usually in the region of 5-100 nm. Silica sol belongs to a colloid.
The grades can be applied in various ways because of its cohesive and adhesive properties.
We produce various Colloidal/Nano Silica products such as silica colloidal, colloidal silica concrete, colloidal silica concrete Densifier, Colloidal Silica Densifier, Polished Colloidal Silica, Colloidal Silica Binders. We are also among best Nano Silica suppliers.Bee Chems.
Silica Sols are defined and characterized on the basis of % silica, alkali %, particle size and particle size distribution and specific surface area of the silica particles.
Charge and Ion modified sols are also produced for specific applications. Recently, non-aqueous sols have also been produced for applications as filler, carrier coating materials etc.
Silica sols can be produced in varied specifications based on following parameters:
(a) Solids %
(c) Particle size/ surface area
(d) Surface modification
