ITC 100 HT Ceramic Refractory Coating (5000°F)

14 items left

Our ITC 100 HT Ceramic Coating is an ultra-high temperature coating applied to ceramic wool (fiber/ blanket/ kaowool), refractory bricks, & castables to protect them from flux, abrasion, direct flames, and oxidization. It also increases efficiency by up to 40%. Rated to 5000 °F, which is nearly double the theoretical combustion temperature limit an atmospheric propane forge.

(Metaphorically ITC 100 does to a propane forge what a turbocharger does to a diesel motor - it's like free power and efficiency.)

Health Benefit of ITC 100:

  • Ceramic wool heated above its rating becomes partially aerosolized and not healthy to inhale (think asbestos).  Wool rated at 2400°F, 2200°F, or 1800°F will look the same as our 2600°F wool, and is fractionally cheaper, but I strongly recommend against its use at welding heats.
  • The next generation of wool refractories being developed are going to be biologically degradable, but they are not yet available at 2600°F heats.
  • Though commonly sought after for its added efficiency and refractory protection, by sealing the flame exposed surface of refractory wool we may one day see ITC 100's greatest value as having been a health benefit.


1.    Reconstitute with water. Mix ITC 100 with 50% water prior to application. Experience has indicated excellent performance even years after reconstituting if it is stored properly (kept cool and well sealed).

2.   Mist lightly with water first. Penetration is best when surfaces are first very lightly misted with water. This helps the ITC to 'wick' deeper into the wool, brick, or castable.

3.   Use a cut-off paintbrush. The consistency is more similar to runny toothpaste than paint. It can be poured with a small 'watering-can' type device in open horizontal applications. Otherwise, its best applied using a paintbrush with bristles cut short to make them stiff. (It can also be sprayed with an air gun in larger applications).

4.   Rigidize the wool first. Applying ITC 100 to a Ceramic Wool Blanket? Try rigidizing the wool first. We sell small bottles of Rigidizer solution for this purpose. (It makes it less like painting cotton balls).

5.   If damaged, simply re-apply as a patch. If the ITC coated surface becomes damaged, another 'patch' coating can simply be applied as needed.

6.  Still have some left over? For long term storage, simply wrap the seal of the lid with electrical tape to prevent evaporation, and insure you remix thoroughly prior to use.
