• ethyl silicate is applied as a primary component of bonding solutions used for ceramic molds production in the process of precision casting;
• ethyl silicate is applied as binding component for heat-proof, chemically stable and weather-resistant finishes. It is also used to obtain a firm solid heat-proof and corrosion-resistant material which cannot be dissolved in water after alkaline hydrolysis and baking;
• it is applied as a binding material for production of dental prosthesis;
• it is applied for wood impregnation, making wood resistant to bacteria influence;
• ethyl silicate is used for improving the quality of rosin varnish;
• it is applied for dehydrated skin tanning in tanning industry.
