Abstract
Novel coating compositions for architectural use are provided, which include a quaternary ammonium silicate having a silica content of 10 to 60% by weight and a liquid epoxide resin, besides the conventional ingredients, such as pigments, fillers, aggregates and water, and which are particularly capable of producing films having excellent adherency to mortar or concrete surfaces. If a stabilized silica sol is added to the compositions, films produced therefrom have much improved resistance to water at low temperatures as well as freeze-thaw stability.
