Kaowool Rigidizer (250 mL Spray) **See Tips**

Kaowool Rigidizer is a popular colloidal silica compound for treating surfaces of ceramic fiber  refractory products (inswool, forge insulation blanket).   It provides a degree of surface hardness, stiffness and resistance to erosion.

 

TIP:

1.   Use in conjunction with ITC 100 HT.

While Rigidizer can't fully withstand metal welding heat, is very popular when applying ITC 100HT.

Application of the famous ITC 100 ceramic reflective paint coating to Kaowool (or similar) is simply easier after it is rigidized.    (It makes it less like trying to paint cotton balls).  

ITC itself is rated to 5000 °F, and by reflecting the heat from the surface of the wool, it tremendously increases forge efficiency, and further preserves the properties of the rigidizer  (and the thermal wool) by mitigating the heat transferred from the firebox.

 

Features:
- Increases surface hardness and resistance to erosion
- Easily applied by brushing or spraying
- Stable & Freeze resistant

 

Key:   A little goes a long way.
