IMPROVE THE QUALITY OF COATING SODIUM SILICATE CONTAINED ZINC

Abstract

The paper presents the quality of mechanical properties of coatings sodium silicate contained zinc using silica colloidal silica and acrylic styrene resin. We found that the increase in colloidal silica makes the module sodium silicate also increase, the pH of the solution decreases, the hardness or the ability to harden faster. With the addition 5% of acrylic styrene resin 48%, the coating sodium silicate contained zinc with higher mechanical properties, particularly adhesion, flexibility of the film.
