Paint for use at 200¦C

Paint for use at 200¦C

(OP)
Can anyone recommend a paint which could be used in a clean room environment at 200°C?

Thanks in advance

RE: Paint for use at 200¦C

Ed,
Do you mean that the Item to be coated will be at 200 Celsius at the time of Application ? or do you mean the temperature at time of application is ambient, but the coating will see service at 200 Celsius, when the item is in operation.

If it is the former, try Belzona for a heat cured material, if it is the latter use an Epoxy Phenolic coating. There are many coating systems out there that will resist 200 Celsius successfully, but not many that can be applied at that temperature.

Let me know if you need further assistance.

Regards,

rembrandt.

RE: Paint for use at 200¦C

What is the paint required to protect from what?
Is the service dry? or is there any sort of chemical exposure.  Must it be conductive?
The help you get depends on the information you provide.

Rembrandt/rustbuster1,

Thanks for taking the time to reply to my question. To clear up a few areas where I was unspecific, the paint/coating I am looking for would be applied at ambient temperature and exposed to 200°C in service in a clean room environment. The paint is to be used to cover an insulation material which can generate dust if disturbed/abraided (it is necessary to occassionally strip down the insulation for maintenance). Adhesion to the insulation substrate is not expected to be a problem. The application is dry and there is no chemical exposure. The paint would need to be non-conductive. I hope this clears things up a little.

Regards

Ed

Many high performance organic coatings will provide the temperature resistance you need - epoxy novolacs, vinyl esters, polysiloxanes, many silicone-rubber based products and even silicates, such as the vehicle for inorganic zincs without the zinc powder added.  
The question is what other properties are you seeking?  
I recommend you check out the siloxane coatings (e.g. by doing that search on Google)first.  You could also visit web sites for coating companies like
International Paint (they have siloxanes and other types),
Ameron
Stoncor, which includes the former Plasite products, including epoxy novolacs and vinyl esters and inorganic zinc/silicates, and
Dow Corning, which specializes in silicone rubber coatings (this is what I think you'll end up choosing).
