Kaowool Rigidizer - Standard -IN store pick-up ONLY (too cold Oct-Apr)

$16.50

** Once Applied, to fully activate the Crystalization Phase - Expose the rigidized wool to a flame for a few minutes.**

This Standard Rigidizer is an economical alternative to Freeze Proof Rigidizer.

A popular colloidal silica compound for stiffening ceramic wool refractory fiber. (Inswool/Kaowool/forge insulation blanket).

CAUTION: Freezing destroys Standard Rigidizer. It solidifies, permanently.

We can only ship this 'Standard' Rigidizer in warm weather.

Order Freeze Proof Rigidizer if you need Rigidizer shipped during winter (Oct-April).

Why Rigidize?

It provides a degree of fibre stiffness, resistance to erosion, and protection from compression, especially before coating with castables (if performed).
While Rigidizer can't fully withstand metal welding heat, it helps give wool integrity resisting compression which would permanently diminish performance.
Applying performance/protective coatings to your forge liner is easier after it is rigidized. (It makes it less like trying to paint cotton balls).
Commonly used prior to coatings like ITC 100HT, ITC 296A or Kast-O-Lite 30 which aid in increasing the efficiency and longevity of your forge.

TIP:

ITC is rated to 5000°F, and by reflecting the heat from the surface of the wool, brings a typical 40% increase of forge efficiency, burning less fuel, & shortening heat up time.
ITC also preserves the properties of the Rigidizer and the thermal wool by mitigating the heat transferred from the firebox.

Typical Applications:

Surface coating for ceramic fiber blanket and modules exposed to high-velocity gases.
Surface treatment for vacuum-formed fiber shapes to increase surface hardness.
Increases surface hardness and resistance to erosion.
Easily applied by brushing or spraying, a little goes a long way.
