Heat-Block heat absorbing compound

The Alvin Products Heat-Block heat absorbing compound is formulated to eliminate and protect metal against heat damage during brazing, soldering, welding and other procedures. Heat-Block protects metal from heat damage and prevents heat from traveling through the metal surface, which can discolor parts and cause damage such as buckling, cracking and warping. To use, apply the heat absorbing paste directly from the container onto the metal and it will absorb and dissipate heat. Heat-Block is a water-based compound and is reusable and is offered in pint, quart, 1-gal, and 5-gal sizes. It cleans up with soap and water.
