High temperature coating/linings

I am also looking for any substance which can give better surface finish than

hot dip galvnising on metal, but I have not heared more than 1300f temperature

I would recommend 840-m HiE-Coat from Aremco

I found the company by doing a search on Globalspec for industrial coatings and then filtering the result by operating temperature in the advanced filter on the left.

Kilns that fire to this temp use a ceramic lining. Fire clay.

Our neighboor produce special firebrick, which can be used for iron mill etc. all sorts of shapes. They supply europe and america etc for many years.

I happened to know the factory when I was asked to test their inspection equipment 4 years ago.

Its the first time I saw various shapes firebrick. originally, I know only rectangle firebrick. but when I went into their workshop, I wonderful found there are lots of shapes objects. Long, round, empty, cylindar etc... I was told they are suit to different spots.

so if you need you can tell me the shape, size and quatity...

beside this firebrick I also went to some ceramic factory which can be usef for high voltage insulation and of cause high temperature, some of them use for super hard material etc. very interesting.

I know these because they all need inspecting for their quality control.

We manufacture a product call Pyrocrete 241 which protect steel structure up to 4 hours in a petrochemical fire situation. We have UL 1709 desing for steel but not for concrete. P-241 can be applied over concrete and will protect your concrete structure. Give me a call if you have an interest in the product; we will see if it can work.

Most any Refractory company can supply and apply a gunite (sprayed on) refractory that can do this. Note: The refractory coating may have to be cured via a controlled heat up and various hold times and temperatures. The concrete may have to be cleaned or sandblasted to have the bite to hold the gunite.

I applyed a coating over a year ago which is withstanding going from -273 F to +3000 F in 1/2 second.
