DRAGON 'Skin' PLUS - Industrial Wool Coating: Protective, Efficient, Thin, Reflective - 3000°F

Dragon Skin is the revolutionary coating for ceramic blanket. Engineered to provide a hard-surfacing, thin skin-coat for refractory ceramic 'kaowool'.  It ensures ceramic wool fibers are not broken down and aerosolized, avoiding asbestos-like inhalation condition risks (remain in your lungs permanently once inhaled). Sealing ceramic wool from open-air fire box exposure is ALWAYS a good idea, especially if you don't know the rating of the wool.

• Engineered in Canada - an industrial pioneering product.
• Dragon skin can be applied as thin as 1/16" thick (up to much thicker if needed).  It adds strength, efficiency, and reflectivity.  
• Unlike classic castables, which only bond to existing surfaces mechanically, Dragon-Skin adds a chemical bonding capacity.

Application: 2 parts. #1 =Dry Part A, and#2 =Wet Part B. 

• large spoon,
• small trowel
• stiff paint brush
• damp burlap/cloth to slow evaporation

Step 1.  Ensure your wool is well rigidized first.Liberally spray your wool with rigidizer, then fire your burner until the dye in the rigidizer becomes translucent. Allow it to cool. 

Step 2.  With a pencil, poke holes in the rigidized wool (creating 'root tracts'), allowing the coating to gain extra grip and increased durability. 

Step 3.Dragon Skin is mixed to a watery blend. Apply it with the aid of gravity. Flip/roll your forge or foundry and apply the coating to the horizontal surface (or lower 1/3 of a curve). 

Step 4. Allow it to soak and stiffen before the unit is rotated to coat another surface. 

Step 5. Once coated lightly, you can apply a 2nd coat where added durability is needed. (IE;  on the lower walls, around side port 'windows', & where abrasion or contact is likely.)

Step 6. Allow the high-moisture mix a few minutes to soak in, cure, and evaporate. The optimal way to promote hardening without cracks is to lightly cover the dragon skin with a damp burlap/cloth to slow evaporation until the castable has acquired some strength.

Set Time:

• Ideally, let the skin air dry for 2 days and then add low heat for a few hours to evaporate any remaining humidity without creating steam. 
• Finally, gradually bring the forge up to half-temp (1200°F) (over a few hours) for hard setting and full strength.

Coverage:   

A small forge can be skinned with a small kit.  Of course, coverage will be doubled when applied 1/16" instead of 1/8" thick.       

Dragon Skin adds radiant heat reflectivity and efficiency to wool insulation. For optimal reflectivity and industry-leading performance, apply a thin (or ultra-thin) coat of ITC-100 HT as a final layer.

Alternatives:

Traditional products like Kast-O-Lite Li 30 Li-G+ & KAST-O-LITE 30 Li work great, but they have to be applied at least 3/8" thick.  KOL adds insulation value and structural substance (more weight). KOL performs best with an ITC-100 HT reflective coating.
