Abstract
A composition for sealing leaks in an engine includes a water-soluble metal silicate, a body of organic fibers, and a body of inorganic fibers. The organic fibers may include synthetic polymeric fibers as well as natural fibers such as cellulose and animal-derived materials. The inorganic fibers may include refractory fibers such as glass, ceramic or mineral fibers. The composition may be prepared in the form of a dry material or as a solution. Also disclosed are methods for using the composition.
