How is Powder Coating Applied?

How is Powder Coating Applied?

Most powder coating is applied electrostatically. Generally, the following steps are taken when applying powder coats to the metal via electrostatic spray:

  • The surface to be painted is prepared via sand-blasting or some other cleaning/etching process to remove contamination that may inhibit adhesion
  • The powder is sprayed through an electrostatic or cornea gun onto a metal surface that is grounded. The electrical charge given to the powder by the gun is attracted to the grounded surface of the metal.
  • The coating is cured at a specified temperature; cure temperatures vary depending on the coating being applied.
  • Further coats are added if required.

Other methods of applying powder coatings include “hot flocking” (electrostatic spray on to preheated surfaces) and fluidized bed dipping.

How Expensive is Powder Coating?

Customers not only want to know how powder coating is applied to metal; they also want to know how much the process will cost. Obviously, the exact cost depends on variables relating to the individual job: how many components need spraying; what area is to be sprayed; what type of coating is required; and how many coats are needed. Generally, powder coating is more cost-effective than painting, as less product is required, and the durability is much better when powder coating is used.

How Expensive is Powder Coating?

Obviously, there is a cost associated with powder coating, but the process normally offers better value than if the paint was used. Because powder coating is economical to apply and also provides a higher level of durability than paint, it is usually a more cost-effective option and offers better value.

Where to Get Powder Coating Done

To get the best result, powder coating requires specialize, advanced equipment and a skilled, knowledgeable team. A specialized powder coating facility is typically the most appropriate place to get the work completed to the required standard.
