Pyroseal is a non-asbestos furnace and retort cement. It is smooth, creamy, easy spreading and sticks where you put it. Pyroseal exhibits superior performance in bonding, controlled expansion and contraction to avoid shrinking and cracking. It is easy to apply even in low, below freezing temperatures.

Characteristics

Contains no asbestos or OSHA restricted fibers

Shrink and crack proof

Low freezing point

Fire proof and acid resistant

Applications Pyroseal is recommended for use on high temperature refractory surfaces found in fireboxes and other parts of furnaces, boilers, stoves and stokers used for comfort heating. It works well on flue pipes, clean outs, ducts and chimney collars. When cured Pyroseal is fire proof, acid resistant, shrink proof and crack-proof.
