ABSTRACT:
This invention relates to the production of chemically durable inorganic silicate coatings which are homogeneous, easy to apply, and exhibit essentially infinite shelf life. More specifically, this invention relates to the preparation of such coatings by incorporating a metal oxide (M.sub.x O.sub.y) wherein Y:X is at least 1.5, into a true aqueous solution of an alkali metal silicate, at least about 50% by weight of said alkali metal consisting of potassium, which will dry in air, i.e., be non-hygroscopic. Thereafter, upon drying and curing, a crystal phase precipitates in situ within the solution causing polymerization of the silica at the crystal interfaces and subsequently throughout the solution, thus yielding a durable coating consisting essentially of a crystal phase homogeneously dispersed in a silicate glassy matrix.
