Abstract
A sprayable, high solids, low-volatiles filler composition is provided which may be used as a coating on a variety of substrates. The sprayable filler composition comprises a first filler/glazing component formed from a mixture of a resin, a filler, a mixture of thixotropic clays, activated fumed silica, hollow glass microspheres, and a ketone solvent. The sprayable filler composition has a second catalyst component. The glazing/filler component is blended with the catalyst component, preferably either internally or externally of the spray nozzle, and the resultant sprayable filler composition is sprayed onto a substrate. The resulting cured coating provides a sandable surface which is corrosion resistant.
