It would be very interesting to know the brandname, especially if it mentions the chemicals used.

Here's a current product. Says it's "a colloidal silica compound for treating surfaces of ceramic fiber products to provide a degree of surface hardness and resistance to erosion."

If you haven't already found your solution, what you are looking for is called "rigidizer". I've heard the types ITC100 and ITC200. It's apparently a brush on/spray on material for coating the kaowool. You really need it around the tangent where the flame is directly impinging.

An extract from Ron Reill's Forge Pages ( http://ronreil.abana.org/Forge1.shtml ) gives useful info on a coating -

A Note About ITC-100 and Kaowool: ITC-100 is more than just a ceramic wool stabilizer. It is an infrared reflector that reradiates up to 98% of the heat that strikes it back into the forge chamber. This will heat your iron faster, and will act like an additional inch of Kaowool, providing lower shell temperature and better fuel economy, as much as 30% better in independent tests. It will also stabilize the Kaowool so that you don't have dangerous ceramic fibers in the forge exhaust. It will last almost forever if it is not damaged through mechanical injury by you or others using your forge. Even though it is semi expensive, it is well worth the cost as it will repay you in various ways, directly and indirectly, very quickly. It may be used on any kind of forge chamber surface, not just Kaowool. Also, if you have metal surfaces in the forge, there are special undercoatings available to bond the ITC-100 to the smooth metallic surface. I should add that this material is not useful in a coal forge.

A quick Google of ITC 100 will show how commonly it is used in the forge and furnace communities,
