Ceramic Fiber Moldable (2300ºF Air-Setting Ceramic Fiber Moldable Putty)



Kaowool® MOLDABLE
  • High-temperature putty
  • Ready to use
  • Easy to apply
  • Air dries and hardens
  • Regular and sticky version (SV)
Kaowool Moldable is a mixture of ceramic fiber, silica binders, and fillers which produces an insulating product with a sticky consistency. This type of mix is ideal for applications such as penetration seals, metal stud protection (as in ceramic cone anchors), and for patching refractory cracks and fissures. The temperature of Kaowool Moldable and any surface to which it is to be applied should be 70ºF (20ºC) or above to ensure proper adhesion.

Drying is possible at room temperature; but depending on thickness, may require an extended period of time. Heated, forced air drying is recommended, This may be safely accomplished at any internal temperature below 212ºF. Ventilation should be provided during drying to exhaust organic fumes resulting from vaporization of certain organic agents.

Installation Information
Kaowool Moldable may be installed with plastic gloves, trowels, spatulas, or a caulking gun. it is easily smoothed to the desired contour by water-wetting the forming tool and molding to shape. Excessive wetting will increase drying shrinkage.



Drying and Firing
Drying and firing conditions are dependent on the mass of Kaowool Moldable. If the mass is small, i.e., less than 1 pound (1/2 kg), it can be fired to its use temperature immediately without damage.
For large masses, the recommended practice is to force dry at 200ºF - 300ºF with a major uncovered surface exposed and adequate ventilation provided. Generally overnight drying is sufficient for thicknesses 1" - 2" (25 - 51 mm).



Note
Cans should be kept sealed to avoid hardening. Kaowool Moldable will be damaged if allowed to freeze.
