Description   KAOWOOL THERMAL CERAMICS RIGIDIZER Rigidizer is a colloidal silica compound for treating surfaces of ceramic fiber products to provide a degree of surface hardness and resistance to erosion. Kaowool Rigidizer is stabilized against freezing during exposure to cold; however, freezing should be avoided. Price shown is per gallon. -Sets with strong, hard film and develops ceramic bond above 1600°F (871°C) -Can be used for spray, dip, or brush applications over fiber blanket, boards, or modules to impart extra strength Features • Increases surface hardness and resistance to erosion • Easily applied by brushing or spraying • Freeze resistant Applications • Surface coating for Kaowool ceramic fiber blanket exposed to high velocity gases • Adhesive for use in making composites and laminates • Surface treatment for Kaowool vacuum formed shapes to increase surface hardness Physical Properties Color clear Solid content, % silica (approx) 28 - 29 Weight per gallon, lb (kg) (approx) 10 (4.5) Nominal density, (wet), pcf (kg/m3) (approx) 75 (1202) Maximum temperature rating, °F (°C) 2300 (1260) Freezing temperature, °F (°C) 28 (-2) Viscosity, centipoises @ 25°C 4 Specific gravity @ 25°C 1.203 pH 9.7 Handling Kaowool Rigidizer must be protected from freezing. Normal shelf life is twelve months in unopened containers that have been properly stored. Installation Information Kaowool Rigidizer is applied by brushing, dipping, rolling, and spraying. Suitable respiratory protection and ventilation are required when applied by spraying. Materials to be rigidized should be free of all grease and oil. Kaowool Rigidizer receives its bonding action from the removal of physical water. Bonding may be accelerated by heating or over drying. Curing is a function of the size of the shape and its geometry. An application rate of one gallon per 25 square feet (7.6 m2) of ceramic fiber surface will render a hard surface without completely rigidizing the interior of the ceramic fiber body.
