How long does powder coating last? This is a question that often plagues those who are considering powder coating for their metal surfaces.
But the answer is more complex than you think. Powder coating is a type of coating that is applied to the metal to protect it from corrosion and wear.
If you are exploring powder coating, you have probably heard about its outstanding longevity. But what exactly does “outstanding longevity” actually mean?
So, let’s examine a few of these variables to get a better answer to your question.
How Long Does Powder Coating Last?
Powder coating can last up to 20 years, but it may deteriorate quickly because of constant use, UV light effects, and the surrounding environment. Powder coating can last for many years if properly cared for.
Powder coating is a metal finishing that is commonly used in the substitution of liquid paint. Apart from liquid paint, it is usually used as a powder that does not require solvents.
The powder coating process involves applying a dry powder on the metal surface and then curling it with heat.
This creates a tough, protective layer resistant to scratches, chipping, and fading.
However, on items that are exposed to the elements (outdoors, in direct sunlight), powder coating may only last 5-7 years before it begins to degrade.
Powder coating is preferred by those looking for a more robust, long-lasting finish.
What Are The Factors That Affect The Lifespan Of Powder Coating?
Powder coating is one of the most durable finishes available, lasting many years. However, several factors can affect the lifespan of powder coating.
Suppose you want to protect your car’s rims from the coating process.
So, how will you protect rims powder coating, and what factors affect the life lifespan of powder coating?
1- Using harsh cleaners or abrasives on your rims. This is the most important factor that significantly affects the lifespan of powder coating. Why?
Using harsh cleaners can damage the powder coating and leave it susceptible to chipping and flaking. Instead, opt for gentle, pH-neutral cleaners designed for powder-coated surfaces.
2- Many people make the mistake of not rinsing their rims after washing them because their powder coating is damaged.
So please rinse thoroughly after washing them to remove any cleaner residue that could damage the finish.
3- Inspect your rims regularly for any signs of wear or damage. If you notice any chips or cracks in the powder coating, have them repaired as soon as possible to prevent further damage from occurring.
These three factors must affect your powder coating lifespan if you do not avoid them.
What Shortens The Lifespan Of Powder Coating?
While powder coating can provide a long-lasting finish, several factors can shorten the lifespan of powder coating.
One factor that can affect the lifespan of powder coating is the type of substrate it is applied to. For example, powder coating applied to bare metal will only last for a short time as powder coating is applied to a primed or painted surface.
Another factor that can shorten the lifespan of powder coating is abrasion from sand, dirt, or other abrasive materials. These particles can wear away at the powder coating, causing it to lose its protective properties.
Additionally, if the item being coated is exposed to direct sunlight or extreme temperatures (hot or cold), the finish will begin to degrade and break down over time. Thus, it also shortens the lifespan of the powder coat.
Generally, when used outdoors, you can expect a good quality powder coat to last 3-5 years on average. And with proper care and maintenance. Such as regularly cleaning and waxing the surface, you can extend its lifespan even further.
How Many Types Of Powder Coating Are There?
There are many types of powder coating, each with its advantages and disadvantages. But how do you know which one is right for you? Let’s have a look.
There are two main types of powder coating. These are:
1. Thermoplastic powder coating:
Thermoplastic powders melt when heated and flow around the substrate during curing; they are typically used for lower-temperature applications.
2. Thermoset powder coating:
Thermoset powders crosslink when heated and cured into an infusible state; they are generally more durable than thermoplastics but require higher curing temperatures.
What Are The Uses Of Powder Coating?
Powder coating is durable and resistant to chipping, scratching, and fading. It can also be customized to achieve various colors and finishes.
Powder coating is also used on metals, plastics, glass, and wood. There are many different uses for powder coating, including:
Powder-coated surfaces are highly resistant to scratches, chipping, fading, and wear and tear.
Powder coatings contain no VOCs (volatile organic compounds) and produce little waste.
3. Improved Quality
With powder coating, the finish has less risk of runs or sags.
4. Color Options
There are thousands of color options available with powder coating. You can also create custom colors by mixing powders. Whether or not powder coating is worth it depends on your project requirements and budget.
In a nutshell, powder coating can last for decades if properly applied and maintained.
To maximize the lifespan of your powder coating, clean it regularly and keep it out of direct sunlight.
Powder coating finishes are among the finest for metal fabrication. If you haven’t used it yet, you have been skipping out over something unique.
If you are thinking about powder coating your metal surfaces, be sure to do your research and find the best company to do the job!
Is powder coating rust-proof?
Yes, powder coating is rust-proof. A powder coating can shield numerous types of metal from corrosion, including rust.
What metals can not be powder coated?
Metals that do not conduct electricity and are said to use filler can not be powder-coated.
Can powder coats be applied over paint?
The short answer is yes. But, there are multiple factors to keep in mind. Powder coat over paint may not have as much longevity as powder coat applied to a dried surface.
Should I hire powder coating professionals?
It is good to hire a professional powder coating company. It requires special tools and skills to be done correctly. You may need to gain the skill to prepare the surface area appropriately or apply the powder coating evenly, which can lead to a low-quality finish. So, it is better to hire a powder coating professional.
