gypsum Tank
Hi All,
Customer needs an anti-stick + anti-wear coating on a tank top surface of size 4.5 meters * 3.5 meters

Please suggest a relevant thermal spray coating.

Thanks

Shantanu

Hi Shantanu,

I assume this is the cover for the tank, and you plan on coating the inside surface? The material inside is Gypsum?

Is there temperature? The wear factor is erosion ?

I would think to use a Ceramic coating, Chrome Oxide, brush polish the as sprayed coating with diamond bristle tool, and then maybe a sprayed Telfon type coating.

Hi Stephen,

Thanks for the reply

Two questions:

As the tank is very large, can we spray Cr2O3 using 6P?
Will we need to cure the applied Teflon coating? Because the tank is large and almost impossible to heat cure....
Is there a stand alone TS coating for this application?

Regards

Shantanu

RE: gypsum Tank
In the paper industry the company called Fluron has some teflon® like products, in spray on with no heat curing, spray on and cured at 250 F, and sleeves, sheets.

(link dead)

Note:
I have not used Fluron, or do I have a relationship with them. However, I have seen samples, and seen jobs in Voith Paper, and other paper companies with the coatings for last 15 years or so.




Fluoro-Coat™ 200

Now available to the paper industry- Field applied roll coatings with excellent release. Resulting from a two year development effort, this product can be field applied in less time than conventional roll coverings made with Teflon®. This coating is ideal for rolls subject to mechanical damage.


"Fluoro-Coat 200™" Advantages:

• Ideal for dryers
• Ideal for pressure sensitive "stickies"
• Offers an alternative to doctoring
• Size press hoods and nozzles
• Curable at normal temperatures
• Saves costly downtime
• Not subject to build-up
• Field applied
• Continuous service at 350ºF
• Intermittent service at 450ºF




"Fluoro-Coat 200™"


"Fluoro-Coat 200™" is a completley different chemistry. It is polymerized to release "stickies", such as duct tape that sticks to DuPont's Teflon® finishes. You have to see the release characteristics to believe it. Try the duct tape test!


"Fluoro-Coat 200™" field applied coating tests are underway in comparison to coatings made with Teflon® that must be baked at 700ºF at an applicator's plant.

Dear Shantanu,
We had coated a PCC Silo in 2011 for non stick and non erosive coating using Glass Flake coatings.
You can give a thaught to it.
