Surface Rigidizer Application

Ceramic Fiber Surface Rigidizer

This is a liquid hardening agent specifically developed to enhance the surface strength of ceramic fiber products. Its primary component uses high-purity Colloidal Silica, containing nano-sized silica particles for excellent penetration and bonding.


When sprayed or brushed onto the surface of ceramic fiber blankets, modules, or boards, it penetrates the fiber layer and forms a hard surface upon drying. This hardened layer effectively resists erosion from high-velocity gas flows within the furnace (Anti-erosion), prevents fiber dusting and peeling, and extends the overall service life of the lining.

  • Anti-Erosion: Significantly improves surface resistance to wind erosion, ideal for areas around burner nozzles.
  • Silica Sol Formula: High-purity inorganic binder; produces no harmful gases at high temperatures.
  • Easy Application: Can be applied directly by brushing, rolling, or spraying.
  • Structural Strengthening: Increases the rigidity and surface hardness of fiber products.

Applications

Around Burner Nozzles

Protects fibers from direct erosion damage caused by high-velocity flame flows.

Surface Strengthening
