Abstract
A sprayable, high solids, low-volatiles 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, a phosphosilicate, and a first organic solvent. The coating also has a second organic solvent component as well as a second catalyst component. The coating as applied to a substrate has a thickness of up to 6 mils without sagging, running or cracking.
