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

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

Rigidizer - generally goes quite a long way. 

If you are applying Dragon's Skin, though, I like to fully rigidize the wool to maintain its thickness while applying this coating which goes on 'very-wet'.  (D.S. leaves a durable, efficient, reflective thin coating with maximal wool adhesion.)

(TIP:  Rigidizer crystallizes when flame-heated, and to a lesser extent, even as it air dries.  It can plug-up the small thumb sprayers on the 250ml bottles.  Sometimes you can unplug these sprayers in a bowl of boiling water, but the 500 ml sprayers work the best.)

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 adds integrity, compressive rigidity, optimizes performance, and maintains thickness.  
• 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, insulating Kast-O-Lite 30, or the thinner Dragon Skin, Alien Skin-90, and ITC 100HT (the optimal reflective ultra-thin finish-coat), increasing the efficiency (30%+), durability, longevity, health & safety 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.

Size Options Available:

• 250 ml bottle - spray top
• 500 ml bottle - spray top
