What temperature do you powder coat ceramic?

Without coating and finishing, the metal production process falls short. In metals, the coating has several uses including enhancing their endurance and functionality. Still, certain coating materials work better than others; so, you should choose one that meets all of your requirements and tastes.

The most often used metal coatings are powder and ceramic. The following is a comparison of ceramic coating against powder coating together with their advantages, disadvantages, and advised uses.

With competitive price and timely delivery, NFJ sincerely hope to be your supplier and partner.

Ceramic Coating

A ceramic coating takes advantage of a clear liquid polymer. Its simple look defines it: basically, the metal is visible through the transparent coating. Furthermore, distinguished by its glossy, dazzling look and great for aesthetic appeal is ceramic coating.

The process of ceramic coating makes use of two techniques:

1. Spray Application:
Usually, large metal pieces are required for the spray application. It means misting liquid ceramic over the surface of the metal. The procedure entails being at temperatures as high as 750 degrees Fahrenheit, hence the pieces must have great heat resistance.

2. Dip-Spin Methodologies
The dip-spin technique is more appropriate for smaller metal components. It means submerging the complete metal item into ceramic liquid, so coating its whole surface. The method makes use of a specifically made bin perforated on the sides and bottom. One also has to be around high temperatures.

Pros:

Among the clearest advantages of ceramic coating are:

• Resistance: Ceramic coating shows great scratch and heat resistance.

• Visual: The original paint of the metal is visible through the transparent coating; its glossy look gives its whole aesthetic appeal a polished and smooth finish.

• Easy Maintenance: Repairing ceramic-coated parts is faster and easier than repairing powder-coated ones.

• Affordable: Reasonably less expensive than powder coating is ceramic coating as well.

The great resistance ceramic coating offers against heat, abrasion, corrosion, chipping, and other damaging elements is its most obvious advantage. Up to 3,800 degrees Fahrenheit is a temperature ceramic coating can survive.

Cons:

• Ceramic coating has one clear drawback over powder coating: limited lifetime. With correct care and upkeep, ceramic coating can last up to five years. By contrast, powder coating has a 20-year or more lifetime.

  
  

When to apply a Ceramic Coating?

Under different conditions, ceramic coating is advised to be used. Most importantly, as it is less expensive than powder coating, it is a great choice if your part has a limited lifespan, and your budget is tight.

Thanks to their great resistance against such elements, ceramic coating is also advised if the metal being covered will be regularly exposed to hostile conditions such as heat and corrosion. Your needs and preferences will ultimately determine whether or not to apply ceramic coating.

Powder Coating

Powder coating combines several colors with polymer resins. The heated, melted, cooled, and subsequently crushed ingredients form the ultimate coating powder. Powder ready to stick to the metal&#;s surface is electrically charged. The powder is then cured by being sprayed onto the metal under compressed air.

Powder coatings cure between 350 and 425 degrees Fahrenheit. Furthermore, important is the surface preparation step, which uses chemicals to clean the metal so it is compatible with the electrostatic painting.

Pros:

Among the clearest advantages of powder coating are:

• With correct care and upkeep, powder coating can last up to 20 years.

• Resistance: Powder coating also resists destructive factors including chemicals, UV light, heat, water, and humidity.

• Visual: Powder coating also comes in different textures, colors, and styles, thereby creating a vivid, opulent visual attractiveness.

• Durability: The longevity of powder coating is its most obvious advantage. The coating may keep its shiny look for up to 20 years and resist heat, chemicals, and physical shocks. By helping the metal withstand these and other harmful factors, the coating also greatly increases its lifetime.

Cons:

• Although powder coating may provide more difficulties during repairs and costs somewhat more than ceramic coating. Its great durability, meanwhile, balances the additional expense.

  
  

When to apply Powder Coating?

Given that powder coating can last up to 15 years longer than a ceramic coating, it is a great choice and highly advised for durability. Given its varied hues and textures, which allow you to paint over the coating, it is also ideal for visual appeal. Moreover, powder coating is rather common for usage with recycled metal.

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.

What is High Temperature Powder Coating?

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:

• Ambient to 200°F
• Up to 500°F
• Up to 800°F
• Up to 1,800°F

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:

General Ambient Temperature Powder Coatings

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.

Fluoropolymer Mid-Range Powder Coating

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.

Specialty High Temperature Powder Coating

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.

High Temperature Ceramic Coating

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.
