Powder coating is a finishing process in which dry, free-flowing, thermoplastic or thermoset powder material is applied to a surface, melted, and hardened into an even coating. This finishing process is suitable for various materials, including metals, plastics, glass, and medium density fiberboard (MDF), and can provide both functional and decorative surface coatings in a wide range of colors, finishes, and textures that are not readily achievable by conventional liquid coating methods.
There are two main methods of powder coating—electrostatic spray deposition (ESD) and fluidized bed application. Either process can produce an even, hard finish which is generally more durable, cost-effective, and environmentally-friendly than a comparable liquid coating. However, while powder coatings demonstrate some advantages over liquid coatings, especially in thick or high traffic coating applications, they are not suitable for all manufacturing applications, such as for thin film or large part coatings. The requirements and specifications demanded by a particular powder coat—e.g., application environment, substrate materials, sizing, costs, turnaround times, etc.—help determine the type of coating process most suitable for use.
While each coating process has its advantages and disadvantages, this article focuses on powder coating, outlining the basics and the necessary components and mechanics of powder coating technology. Additionally, the article explores the benefits and limitations of the process and provides some of the considerations manufacturers must keep in mind when choosing a coating service provider.
Powder coating has grown in popularity over the course of the last fifty years. It has become one of the most common methods used to finish automotive and other parts. Every day, more and more people are learning about the many benefits of powder coating over traditional liquid painting. While there are some drawbacks as well, advances in technology are making powder coating a viable alternative for many applications.
