Abstract
Abstract New compositions of matter are made available which contain silicate esters and an alkaline material, the mixtures being kept anhydrous until their use. The compositions are zinc-rich paints, a silicate ester and an alkaline material mixture being mixed with zinc dust. Upon use, the blend is spread out as a coating. Upon exposure to the moisture in air, drying occurs rapidly with the formation of very hard finishes that greatly resist cutting by sharp edges.
