ZRCI Refractory Sheet Types RS-Cloth and RS-Tape are fiber reinforced alumina composites in a highly flexible form. They are received dried, when wet with water or AL-HARD Hardener they become extremely flexible. They can be wrapped into many simple or complex shapes and will stick to themselves. When dried they become an extremely hard, strong, self supporting composite structures. RS-Putty can be used to burnish any surface and provide a very smooth hard finish. After a low temperature bake-out of 300°C (570°F) RS-Cloth and RS-Tape are unaffected by moisture.
They offer the strength, durability, flexibility and versatility required by many high temperature applications up to 1300°C (2373°F). Their high alumina content makes Refractory Sheet RS-Cloth and RS-Tape highly resistant to many environments including Hot Glass handling, molten aluminum and chemical and petroleum processing. After they are baked out they are not affected by water as well as many types of fuel oils.
When hardened with AL-HARD Refractory Sheet RS-Cloth and RS-Tape become “rock hard” for greater strength.
