ABSTRACT:
Curable compositions which form cured products having excellent durability, stain resistance, resistance to heat and flame, and water resistance as well as other desirable properties are prepared by forming aqueous solutions of water-soluble silicates and water-soluble latent insolubilizing agents formed from a metal ion selected from the group consisting of Al.sup.+++, Fe.sup.+++, Cr.sup.+++ and Sn.sup.++ and a ligand selected from the group consisting of ethylenediaminetetraacetate, diethylenetriaminepentaacetate, N-(hydroxyethyl)ethylenediaminetriacetate, nitrilotriacetate and 1,3-propanediaminetetraacetate.
The compositions have excellent stability and may be employed in various applications such as coatings, castings, and molding applications. The compositions are particularly useful in coating applications.
