TGS-25 surface enhanced colloidal silica, the modified colloidal silica of organic molecular polymers, with milk white appearance, has improved the defect of colloidal silica easy to be cracked when coating.
Coating evenly, it can be used as surface enhanced coating in casting to enhance the degree of finish of surface and improve high temperature resistance capacity so as to increase the one-pass rate of finished products and reduce the working time and the cost of sand cleaning.
It also can be used for automobile coating and other coating materials to increase the wear resistance and corrosion resistance.
