Nanoparticles of soluble alkaline silicates as corrosion inhibitors in water based polymer dispersions

摘要

The present paper shows that soluble alkaline silicates, for example sodium silicate, act as flash rusting inhibitors, while aqueous dispersion binders were used in primer paints. Sodium silicate, potassium silicate and lithium silicate were studied for this purpose. Their inhibiting properties were described with the aid of a scanning method, determination of metal weight loss and SEM. Sodium silicate was identified as a very good flash rusting inhibitor for applications in styrene acrylate water borne paints.
