Powder coating&#;s durability and affordability have made our high temperature powder coating a favorite amongst our clients. With its ability to adhere strongly to most metals, it is a great option to consider for your upcoming project. And, if you&#;re wondering whether or not it&#;s heat resistant, the short answer is, &#;yes&#;.

The long answer is a bit more detailed, so please continue below to learn about some of our high-temperature powder coating options.
Powder coating is one of the most common coating methods that professionals turn to when they require fast, even, and reliable industrial finishing. Applied as a free-flowing dry powder, the coating provides unparalleled versatility thanks to its easy application. Unlike conventional liquid paints, which require an evaporating solvent for application, powder coating uses electrostatic application methods before being cured under high heat. Most powders require baking at around 350-400 degrees Fahrenheit for 10-20 minutes to fully cure.
Here at Crest Coating Inc., we have a variety of different high temperature coatings available, and bring our long history of experience and expertise to help our clients find the right products for their specific needs. Thanks to the high temperatures at which it is cured, powder coating is viable in conditions that may not be suitable for other coating techniques. From exhaust and mufflers to heat shields and industrial equipment, high-temperature uses are completely viable. But just how far does that heat resistance go? The truth is, a powder coating&#;s heat resistance varies with the materials that are used. An epoxy coating will be very different from a nylon, fluoropolymer, or ceramic coating, for example.
There are four heat resistance categories that powders will generally fall under:
So, depending on the temperatures and environment you expect to see, we have a range of coatings that we can recommend. Read below to see a few examples:
The most common powder coatings can withstand temperatures between ambient to 200°F, although most are on the lower end of the spectrum. These general powders will do the trick for most typical applications, but may be susceptible to significant color change and other issues once you start pushing that 200°F+ range. As a rule of thumb, general powders can be used on most external components without a problem, but should be avoided when temperatures are expected to exceed 150°F, like engine components or exhaust parts.

The next level up with regard to heat resistance is the use of Fluoropolymer coatings. Fluoropolymers are a family of plastic resins which are based on fluorine/carbon bonds. This coating is characterized by its multiple carbon&#;fluorine bonds, and is often most commonly seen on Teflon coated frying pans. These are usually rated between 300°F to 500°F and are a great choice if additional properties are desired like non-stick performance, chemical, or abrasion resistance. Some fluoropolymer powder coatings are also commonly used on exterior applications of commercial and residential high-rise buildings.
Need even more heat resistance? That&#;s going to push you into specialty high temperature powder territory. The specialty high temperature powder coatings we have available are rated between 600-800°F, and withstand these higher temperatures while still offering good corrosion resistance and some unique cosmetic options. These are ideal for protecting the exhaust components we mentioned earlier on, as well as heater shrouds and other commercial products from high-temperatures. Despite the high temperature rating, high-temperature powder coating is not recommended for direct flame exposure.
Ceramic coatings are the highest heat resistance category readily available to be applied by coating. Rated to temperatures up to 1,800°F, this is the ideal material to use when your project involves extreme heat environments. High temperature ceramic coatings can also perform as a thermal insulator, reducing the amount of heat that radiates from a surface &#; making them ideal for the most demanding automotive, aerospace, and industrial applications. Furthermore, many of these coating options only require an ambient cure, and possess excellent wear properties, allowing them to be applied to a wide range of substrates. Their versatility and strength are why ceramic coatings are often found in sub-sea applications, in your engine compartment, in aircraft, and basically anywhere that you&#;ll find extreme levels of heat, pressure, and friction.

Heat-resistant powder coatings are a specialized category of protective coatings that can thwart high temperatures while providing long-lasting performance in environments where extreme weather is a constant challenge. These coatings have exceptional resistance against heat-induced degradation, adding to their appeal in various applications.
This product can maintain its structural integrity and appearance in a variety of circumstances, making it the go-to choice for domestic and industrial applications where surfaces or components frequently encounter a lot of heat. Understanding the various types of powder coating, their applications and which industries they thrive in will help the end user make informed decisions about which type to invest in for their products.
One key difference between powder coatings and paint is that the former is applied in its solid form and does not emit volatile organic compounds (VOCs). Heat-resistant coatings are specialized, protective finishes that can withstand heightened temperatures. These coatings ensure that coated surfaces maintain their appearance and integrity in most temperatures and environmental conditions. They form a formidable barrier when used as a dry powder and cured in baking.
The primary purpose of heat-resistant coatings is to protect surfaces from damage due to heat, deterioration, corrosion and discoloration in the following industries and more:
These powder coatings can resist high temperatures in various applications by incorporating heat-resistant silicone resins. While there is not necessarily a &#;best&#; heat-resistant coating, several types of heat-resistant powder coatings are on the market, each with its optimal application use:
With powder coating complementing materials like aluminum, iron, steel and zinc alloy, temperature tolerance is a critical factor. The performance of heat-resistant powder coatings in terms of thermal reading, depends on the makeup and end use of the powder coating product. Generally, temperature resistance sits comfortably at 0 degrees Fahrenheit and extends to 200 degrees Fahrenheit, with intermittent spikes between 350 and 400 degrees Fahrenheit.
There are several steps to the application of powder coatings. Throughout these procedures, it is vital to set safety precautions to protect workers from harmful chemicals and ensure an overall safe working environment. The application process involves several key steps to provide an effective and durable finish:
Heat-resistant powder coatings have a few key performance characteristics that add to their value in industrial and domestic applications. Apart from their heat resistance, they also offer protection against chemicals, environmental factors and corrosion. Users can choose from various finishes and colors for long-lasting performance and aesthetic appeal.
While this product is made to withstand high temperatures and extreme environmental impacts, it is essential to properly care for products with heat-resistant coatings to support their durability. The durability of these coatings largely depends on factors like application quality, coating formulation and exposure to extreme heat and environmental fluctuations. These coatings have been reported to withstand 1,000 hours of a salt spray test on airplane parts with no clear indication of corrosion. Regular inspections will help detect any potential signs of wear or chipping.
Maintenance on heat-resistant powder coatings can involve recoating areas with cracks or doing touch-up work. Stay away from cleaning this coating with harsh chemicals or abrasive cleaners, as that can damage the coating. Gently rinse with mild, soapy water and a soft brush and dry the surface after cleaning. Generally, the coating should keep its appearance and integrity for several years with proper maintenance.
Heat-resistant powder coatings are a formidable solution to help safeguard surfaces against extreme temperature conditions. From automotive exhaust systems and household appliances to industrial machinery and architectural applications, these coatings add to the durability and protection of surfaces under demanding circumstances.
