La description
 Characteristics
1 colloidal Silica  belongs to adhesive , liquid silica.
2 It is odorless, tasteless and non-toxic.
3 Its chemical molecular formula is SiO2*H2O.
4 Since the colloid grains are minute (****0nm) and have
relatively larger specific surface area, the grains themselves
are colorless and transparent, so they do not affect the natural
color of the materials to be covered.
5 With low viscosity, it can soak the places where water soaks,
therefore, it shows excellent dispersion and permeability when
 mixed with other substances.
6 Â When the moisture contained in colloidal silica is
evaporated, the colloid grains firmly adhere to the material
surface and the combination of silicon and oxygen is then formed
between grains. It is a good adhesive.Â

Usage
Used as the cohesive agent for various fire-proof material. It
has high bonding strength and high heat-resisting performance
(********0), etc.
Used in coating, painting  industry, it makes the paints
more firm. It also possesses features, such as
anti-contamination, dust-proof, anti-aging, fire-proof, etc. Used
in precision casting of thin, it covers to increase the cover
strength, improves the casting smooth finish. Its molding quality
is better than that of water glass. It can be used to replace
ethyl silicate for molding so as to reduce the cost and help
improve the operating conditions. Having large specific surface
area, colloidal silica can be used as catalyst , binder and
 catalyst carrier. Used in paper-making industry, it can be
used as the anti-glutinous agent of cellophane, pre-treatment
agent of photographic paper, skid proof agent of cement bags,
etc. Used as sizing agent in textile industry, when used with oil
agent to process wool and rabbit hair, it helps improve the
processing of wool and rabbit hair, remove  broken ends,
eliminate flying, thus improve the finished product rate and
increase the economic returns. Used as the treatment agent of
silicon steel plates, dispersing agent of kinescopes and skid
proof agent of floor waxes, etc.
