repair compound - withstands 1000 deg. 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 1000
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
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.
Hi-Temp Lab-metal must be stirred thoroughly before use. No additive
is needed; the repair compound hardens upon exposure to air. Hi-Temp
Lab-metal is a viscous but easily spreadable paste. Upon opening
the can, if the Hi-Temp Lab-metal appears stiff, stir in a capful
or two of Lab-solvent to restore the product to its appropriate
consistency. For any application, the surface must be clean and
dry; free of paint, oil, dirt, and any extraneous materials. Roughening
the surface provides superior adhesion. Hi-Temp Lab-metal's shelf
life is one year in factory-sealed cans. Store in a cool place.
See MSDS for safe handling.
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

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
In order for the hardened Hi-Temp Lab-metal to withstand exposure
to 1000 deg, it must be exposed to a minimum temperature
of 425†F for a period of at least one hour. (The curing
process may be achieved by a more gradual "heat-up", as
in the repair of an industrial oven. 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:
- foundry core boxes
- duct work
- mufflers, exhaust systems, engines
- wood and coal burning stoves, grills, industrial ovens
- dented metal, prior to powder coating -
Lab-metal cannot be used due to the extreme temperatures.
