High temp ceramic coatings can be used for equipment that reaches intense levels of heat, like kilns, ovens, furnaces, forges, and more. There are many different types of high temp coatings all with different characteristics. You want to make sure you select the right coating for the job, and here are some factors to consider to help you do just that.
When selecting a high temperature ceramic coating, the operating temperature range should be the first factor you consider. At lower temperatures, like below 400 degrees Fahrenheit, organic materials can be used. Using the organic materials with inorganic materials in high temp ceramic coatings can provide many benefits. Above 400 degrees Fahrenheit, organic materials break down. Because of this, inorganic materials are essential. The average kiln can fire up to 1,800 to 2,400 degrees Fahrenheit, so high temp coatings are certainly needed.
Another factor you should consider when selecting a ceramic insulation coating is the application characteristics. There are many "thin-film" coatings on the market today that require a relatively thin film in order to stay flexible at high temperatures without cracking. That being said, thicker film options are typically preferable. Thick film or high build high temp ceramic coatings exhibit superior flexibility to allow for higher film builds in intense temperatures.
There are three main categories when it comes to the coating environment, and they include indoor, light outdoor, and heavy outdoor. Indoor high temp coatings needs include stoves, fireplaces, etc. A lighter grades coating option will suit indoor needs. Light outdoor use includes grills, smokers, fire pits, etc. These services require a heavier grade coating to stand up to UV rays and rainwater. Heavy outdoor services are considered extremely harsh and require industrial high temp ceramic coatings. The automotive service industry is an example of heavy outdoor use.
Finally, you should consider aesthetics when selecting your coating. Color stability in high temp coatings can vary between manufacturers, so you want to select a coating that's rated for your highest temperature as well as color stable to that temperature.
