Abstract
A method of heat-sealing substrates, particularly glass to glass or glass to other materials, which comprises using as a heat-sealing medium a silicic acid heteropolycondensate prepared by hydrolysis and polycondensation of at least one organosilane and at least one component selected from the group consisting of silicon-functional silanes, substantially involatile oxides soluble in the reaction medium, or compounds convertible thereto, and organofunctional silanes. The heat-sealing bonds obtained are strong, durable and moisture resistant, the excellent moisture resistance being of special benefit in the heat-sealing of glass substrates.
