Hi-Temp Lab Metal Filler 14oz

PRODUCT CAN ONLY SHIP UPS GROUND. NO INTERNATIONAL SHIPMENTS

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

(see “Drying time’), 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 with

powder or liquid coatings.

Preparation

Hi-Temp Lab-metal must be stirred

thoroughly before use. No additive is

needed; the repair compound hardens upon

exposure to air. The viscous, easily

spreadable paste may be thinned. Upon

opening the can, if the Hi-Temp Lab-metal

appears stiff, stir in a capful or two of Labsolvent.

The application surface must be

clean and dry; free of paint, oil and dirt.

Roughen the surface for superior adhesion.

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 at room

temperature, and heat harden prior to each

additional coat.

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. Dip the brush into Lab-solvent

periodically to keep the bristles free and

prevent clogging.

Drying time

 Depth of application determines drying

time; hardening occurs by exposure to air.

Apply no thicker than 1/4 inch per

application. The application must air dry for

at least 24 hours, or until the product has

hardened to a metal state. It must then be

heat cured (before applying a second coat).

To heat cure:

After fully hardened, Hi-Temp Labmetal

must be heat hardened by exposing

it to a temperature of 425ºF for 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.) Heat hardening must be completed

prior to powder coating.

How to determine which product to use for

high temperature applications

 • For powder coating processes at

temperatures less than 350oF, Lab-metal

may be used (even for multiple oven

passes).

 • For powder coating processes in which

the metal parts will never be subject to

temperatures higher than 425oF, for

durations no longer than 20 minutes, for

no more than one oven pass, Lab-metal

may be used.

 • Hi-Temp Lab-metal  must be used in

powder coating processes running at

temperatures above 425oF.

 • Hi-Temp Lab-metal  must be used if a

part is to be exposed to temperatures

above 350oF for more than 20 minutes in

duration (or multiple high-heat

exposures).

 • Hi-Temp Lab-metal  must be applied in

thin layers and allowed to air dry for at

least 24 hours, then heat cured as

instructed on the label. If Hi-Temp Labmetal

is not completely dry when subject

to heat, and if the product is not properly

heat hardened, outgassing or bubbling

may occur.
