Kaowool Pumpables are water-based, pliable, putty-like materials composed of high temperature ceramic fibers, organic polymers, inorganic binders, and other proprietary ingredients. They are supplied premixed and ready to install from straight-sided 5-gallon pails using the HS-100 Extrusion or similar pump. Kaowool Pumpables can be used in hot or cold repairs of any deteriorated back-up insulation in ovens, furnaces, boilers, and process equipment, and as a hot-face repair of any cracks or gaps in existing refractory due to shrinkage. Kaowool Pumpables when dried form a hard rigid mass that provides good insulating properties, good strength and vibration resistance.
