Difference Between Powder Coating and Epoxy Coating

Difference Between Powder Coating and Epoxy Coating

You may have wondered what the difference is between powder coating and epoxy coating. What are the benefits of each type of coating? The type of coating you use can depend on the object you are coating and what the object will be exposed to throughout its service life. Your personal preference regarding these coatings may determine your decision as well. At Secoa Technology, we offer a range of coating solutions for various industrial applications.

Powder Coating

As an advanced method of applying a protective and decorative finish to a metal surface, powder coating is beneficial for individual consumers and heavy industry. The powder applied consists of a mixture of minute particles of resident pigment that are sprayed electrostatically onto a surface. The powder particles which are charged stick to the electrically grounded surface before the powder is heated and then fused with a curing oven into a smooth coating. The finished product is a high-quality, durable, attractive, and uniform finish.

Businesses, consumers, and industries can take advantage of powder coating as an economical and long-lasting finishing solution that can be used on a variety of metals. Surfaces that are powder coated are highly resistant to various types of wearing, chipping, fading, and scratching as compared to other types of finishes. You can take advantage of various color and texture selections with this type of coding as well.

Epoxy Coating

Epoxy is a tough and multi-purpose material consisting of the cross-linking of an epoxy resin and hardener or co-reactant. It has been used in applications involving steel pipeline coating, concrete floor paint, and even heat shields for space capsules. It offers many benefits for industrial and commercial painting applications. These benefits include:

  • Easy to remove from a surface, but remains adhered otherwise
  • Highly resistant to flaking, cracks, chipping, and peeling
  • Solid temperature resistance – is able to resist heat and cold better than most paints
  • Easy to repair
  • Useful for applying cosmetic changes, such as pitting, to create a smoother finish
  • May be submerged in salt water for years without experiencing damage to the finish
  • Non-toxic and environmentally friendly – it does not easily erode or dissolve into the environment

You will be hard-pressed to find the perfect coating that can handle all types of surfaces and applications. Therefore, it’s important to understand the needs of your specific application before choosing a coating.
