CERAhard™-CFH (Ceramic Fiber Hardener) Is an inorganic liquid hardeners. They are generally used to increase the durability and surface erosion resistance of Ceramic Fiber blanket and board products. CERAhard™-CFH hardener contains an inorganic wetting agent to promote saturation into the substrate and tends to remain on the material surface of the product form to which it is applied.

CERAHard™-CFH is a specially prepared solution used to hard the surface of Ceramic Fiber blankets, board, modules and to improve resistance to high gas velocity. It can be applied by spraying on the surface of the ceramic fiber product. It is used to make hard surface of Ceramic Fiber Board hence rejection level due to the hardness is reduced. Recommended use temperatures for all Harden blankets, modules and Boards are 75ºC less than the normal use temperatures.
