    GS-30 Series

    Colloidal silica GS-30 series have the advantages of low impurity content, compact structure, uniform size, good controllability of physical and chemical indexes and high temperature resistance, which can improve the quality of casting.

     

    According to the properties of high temperature strength, and the size of particles,we have the five types.
