Hi-Temp Lab Metal® - Permanent Repair Compound - Withstands 1000°F
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°F. Applied 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.

Lab Metal® Solvent
Thinner for Lab-metal and Hi-Temp Lab-metal, and metal cleaner. Lab-solvent cuts grease, oil and dirt, and is recommended as a metal cleaner and degreaser to prepare surfaces for Lab-metal and Hi-Temp Lab-metal applications. Removes paint quickly and efficiently. Lab-solvent thins Lab-metal to paint consistency for brushing or spraying a metallic coating. To prevent hardening of Lab-metal and Hi-Temp Lab-metal in the can, wet the surface of the metal repair compound with Lab-solvent and cover tightly after each use.

Lab Metal® Heat Block
Heat Block is an insulation compound with unique heat absorbing properties which insulate against heat transfer during welding, soldering, brazing or other heat treatment. The heat absorption properties protect closely soldered parts, valve gasketing, thin gauge metal, and other materials which could be damaged during repair or installation work. HEAT BLOCK is used to protect plastic drain pipes in close proximity to metal pipes being replaced or soldered. HEAT BLOCK prevents distortion to light gauge metals, protects rubber and plastic components, and painted or finished surfaces while soldering, brazing or welding.
