Curable compositions comprising aqueous solutions of water-soluble silicate and water-soluble zincate latent insolubilizers

摘要

Curable one-package compositions which form products having excellent water resistance as well as other desirable properties are prepared by forming aqueous solutions of water-soluble silicates and water-soluble zincate latent insolubilizers selected from the group consisting of alkali metal or quaternary ammonium zincates having dispersed therein certain inorganic pigments, preferably TiO2. These curable compositions may be employed in a number of applications such as, for example, coatings, castings and moldings, but they are particularly useful in protective and decorative applications.
