High Temp Lab Metal

Permanent repair compound – withstands 1000ºF. Hi-Temp Lab-metal is ready-to-use right from the can. Developed for difficult repairs subject to excessive heat, Hi-Temp Lab-metal withstands temperatures as high as 1000ºF

Lab-metal may be thinned to paint consistency with Lab-Solvent (sold separately), and brushed or sprayed on practically any surface to provide a rustproof, water-resistant, hard metal finish. Use the Lab-Solvent (sold separately) to thin Lab-Metal, clean the application surface and create a glass-smooth surface to minimize sanding. (Add Lab-solvent to extend storage-time). Store in cool place.

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 Lab-solvent over the remaining Hi-Temp Lab-metal contents, then cover tightly. (Stir the solvent into the Hi-Temp Lab-metal before using again). Lab-solvent is also used to thin Hi-Temp Lab-metal for brush-on applications.  Hi-Temp Labmetal must be heat hardened by exposing it to a temperature of 425ºF for one hour.

Application

Hi-Temp Lab-metal may be applied with a putty knife, spatula, trowel, caulking gun, or rubber squeegee. When filling deep holes or cavities, the putty should be applied in thin layers, less than 1/4″ thick. Allow each layer to dry for at least 24 hours. Dry time may be accelerated with force curing, infrared lamps.This depends on air temp, type of metal.

To apply Hi-Temp Lab-metal with a paint brush, it must be thinned to paint consistency with Lab-solvent, then applied with light brush strokes; not worked over as with paint. Dipping the brush into Lab-solvent periodically will keep the bristles free and prevent clogging.

Depth of application determines drying time; hardening occurs as the diluent evaporates. The application must air dry for at least 24 hours, or until the product has hardened to a metal state.

In order for Hi-Temp Lab-metal to completely harden after a 24 hour air dry time, it must be exposed to a minimum temperature of 425ºF for a period of at least one hour depending on thickness of application. (The curing process may be achieved by a more gradual “heat-up”, as in the repair of an industrial oven or exhaust. In this case, as the oven is heating, the Hi-Temp Lab-metal repair is curing.)

Hi-Temp Lab-metal is recommended where original Lab-metal may not withstand the extreme heat. Originally developed due to requests from the foundry industry, industries such as metalworking, powder coating, welding, fabricating, heating, construction, auto repair, die casting, mold refinishing, and sheet metal production and finishing have found uses for Hi-Temp Lab-metal. It successfully repairs:

Durability
Hi-Temp Lab-metal adheres to most metals. Once hardened, it can be machined, ground, filed, and sanded. Buffed to a satin smooth finish, Hi-Temp Lab-metal leaves an undetectable repair. 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 painted over — even powder-coated.
