Are you considering a high-quality powder coating? Want more confidence in the coating you already have? Knowing more about the powder coating on your equipment can help you maintain it for longer, getting more out of the durable finish. So, if you are asking, “How long does powder coating last,” you will have your answer alongside other powder coating longevity tips and tricks.

When you want to see your equipment last longer, look better, and be protected from corrosion and rust, come to Precision Coating Technology & Manufacturing.

How Long Does Powder Coating Last?

Typically, a fresh coat of powder coating lasts for 15 to 20 years. This could be up to 40 years, but this level of durability is rare and would depend on several factors. Are you using the equipment for outdoor applications? Is the coating exposed to moisture or chemical factors? What kind of coating is it? Even before your coating is applied to your equipment, the method and quality of surface preparation can enhance or detract from the final coating.

Many factors affect powder coating longevity, and depending on your goals and the use of your equipment, you could expect a very long and productive product lifetime!

What Affects Powder Coating Lifespan?

Several factors can affect your powder coating. While these powerful protective layers ward off the worst of things like abrasion, impacts, and other common damage, nothing can provide a perfect protective layer. These are the biggest threats to your powder coating’s lifespan:

Temperature

Temperature is a common threat to powder coating, particularly high or low temperatures. Most powder coatings are most stable in standard living temperatures – around 70° to 80° F (21° – 27° C). If your powder coating is regularly exposed to extremely high or low temperatures, you can expect to see it last a shorter period.

UV Radiation

UV radiation – from the sun or UV lights, commonly damages powder coatings over time. The largest issue you might see if your powder-coated equipment is exposed to UV is color leeching. Outdoor applications can reduce your coating’s lifespan, though the value you receive might still be impressive.

Humidity

While most powder coatings are designed to be waterproof, protecting metal surfaces from long-term corrosion, they may also experience negative effects from humidity. High humidity for long periods may begin to absorb the coating, affecting its appearance and durability.

Corrosion

Lastly, there are many harsh chemicals that may cause harm. Strong chemical cleaners and solvents may corrode a powder coating with repeated exposure. When cleaning your equipment, mild soap and gentle cleaning agents are usually sufficient.

Note that not all powder coatings are made equal. For instance, we offer fluoropolymer and plastisol coatings. The first is very resistant to chemicals and temperature changes and is commonly used in cookware. Plastisol is a UV-resistant and soft powder coating that is frequently used on playgrounds. When getting a powder coating, discuss your goals, uses, and the needs that you want met.

How to Get The Most From My Powder Coating?

Proper maintenance is always going to be the first answer when you ask how to promote a longer lifespan. Regular maintenance should include regular cleaning with gentle cleaners and non-abrasive cleaning tools. Cleaners that are strongly basic or acidic should be avoided, as should aggressive scrubbers like steel wool.

In the long term, regularly inspect your tools and equipment for cracking or peeling, particularly around high-use areas such as handles. When not in use, you should store items in room-temperature areas and avoid exposure to harsh chemicals.
