How to Choose What Powder to Use for Your Project

Determine what type of powder will work best for your specific project.

Understanding Different Types of Powder Coatings

When it comes to choosing the right powder coating for your project, it's important to understand the different types available. There are five main types of powder coatings: epoxies, polyesters, epoxy-polyester hybrids, fluoropolymers, and urethanes. Each type has its own unique characteristics and advantages, which we will explore in this article.

Factors to Consider When Choosing a Powder Coating

There are several factors to consider when choosing a powder coating for your project. These factors include the intended use of the coated object, the environmental conditions it will be exposed to, and the desired appearance and durability of the coating. By carefully considering these factors, you can select the powder coating that best meets your project's requirements.

Polyester Powders

These are the most used powder today. They offer many advantages. They come in the largest selection of colors, glosses, and specialty types. They are usually value priced compared to some other powders. They can have lower cure temperatures. They also are less likely to yellow when left in the oven too long. They work well indoors and in some outdoor situations as they can offer up to three years of strong UV resistance.

Epoxy Powders

Epoxy powders are extremely durable and hard after curing. They offer great resistance to corrosion and chemicals. They adhere to metal very well, and are popular to be used as a primer, under other powders. Epoxies are a great choice when looking for a coating that will be used indoors.

Epoxy's weakness is that they don’t do well outside. In a short amount of time, they will fade and chalk.

Epoxy-Polyester Hybrids

As the name states, they are a blend of epoxies and polyesters. Their main benefit is they are similar to epoxy powder with the added advantage of being able to stand up to the outside elements a little better than a straight epoxy. The disadvantage is their reduced corrosion and chemical resistance.

Fluoropolymers

Fluoropolymers are very popular in architectural settings. They are incredibly weather resistant. They are great in outdoor settings because of their corrosion resistance, and they retain their color and gloss.

Urethanes

Urethanes are also great for exterior products. They have excellent chemical and corrosion resistance. They are most often used in HVAC, agricultural, exterior hardware and automotive products. Their drawbacks are difficulty in thick mill applications and are more expensive than other powders.

Final Thoughts:

In conclusion, choosing the right powder coating for your project is essential in ensuring the longevity and quality of the finished product. Consider factors such as intended use, environmental conditions, and desired appearance when making your selection. Whether you prioritize UV resistance, corrosion resistance, or durability, there is a powder coating that will meet your project's requirements.
