Abstract
A fire retardant coating composition useful as a paint or as a mastic is composed of ultrafine pulverized fly ash, a low viscosity vinyl acrylic type emulsion polymer as a binder and water. The composition also preferably contains one or more of a dispersant, a defoamer, a plasticizer, a thickener, a drying agent, preservative, a fungicide and an ingredient to control the pH of the composition and thereby inhibit corrosion of any metal surface to which the composition is applied.
