    Specifications

    used for adhesive,batterybeverage&water treatmentcatalyst,ceramics,cleaningconcrete&well cementingcorrosion control coat

    ???????? ???

    Colloidal silica is used alone or in formulations to coat mineral surfaces to improve the corrosion resistance and durability.


    Colloidal silica is used in inorganic paint like silicate paint and can easily be formulated with potassium silicate as the main binder.

    ?In silicate paints, colloidal silica reduces the alkalinity and water absorbtion and improves the anti-soiling properties.?

    It also helps reduce internal stress by reducing the shrinkage in the coating.? Surfaces that can benefit from these coatings include all forms of natural stone and masonry.?

    A coating with colloidal silica will give years of protection and reduce the need for maintenance and other restoration work.
