Hi-Temp Lab-metal is recommended where original Lab-metal may not withstand the extreme heat. Originally developed to meet foundries' core box repair needs, industries such as metalworking, powder coating, welding, fabricating, heating, construction, auto repair, die casting, mold refinishing, and sheet metal production and finishing now rely on Hi-Temp Lab-metal. Hi-Temp Lab-Metal Repairs: Foundry core boxes Duct work Radiators Molds Mufflers, exhaust systems, engines Wood and coal burning stoves, grills, industrial ovens Dented metal, prior to powder coating Easy To Use: Hi-Temp Lab-metal is applied directly from the can with a putty knife or similar tool. No two-component mixing or measuring is necessary. Many applications may be made from a single can. After each use, to prevent Hi-Temp Lab-metal from hardening in the can, pour a small amount of Lab-solvent over the remaining Hi-Temp Lab-metal contents, then cover tightly. (Stir the solvent into the Hi-Temp Lab-metal upon opening container). Durable: Hi-Temp Lab-metal adheres permanently to any clean and dry metal, wood, hard plastic, glass, plaster, or porcelain surface. Its strong bond withstands vibration and other difficult conditions. Once hardened it can be machined, ground, filed, and sanded to a smooth finish. Hi-Temp Lab-metal is impervious to the attack of rust, rot, and mildew. It is not affected by varying climatic conditions, and the hardened metal can be coated withpowder or liquid coatings. Shelf Life: Hi-Temp Lab-metal is guaranteed for one year in the factory-sealed can. Add Labsolvent (as instructed) to extend storage time. Once reopened, the contents should be thoroughly stirred.
