As described by ThomasNet in the article “Understanding Powder Coating,” this innovative finishing process applies a dry powder paint to a surface, which is then heated and hardened to create a durable, protective layer. Powder coating is widely used on metals but can also be applied to plastics, glass, and engineered fiberboards. It provides a robust, visually appealing finish that effectively shields underlying surfaces from damage.
Powder coatings are categorized into two types:
- Thermoplastic Coatings: These coatings soften when heated and can return to their original state upon cooling, making the process reversible. They offer flexibility and are ideal for applications where re-coating or reshaping might be required.
- Thermoset Coatings: These coatings undergo a chemical reaction when heated, forming a durable, non-reversible finish. Known for their thinner application and high-temperature resistance, thermoset coatings are widely used in demanding environments.
Both types offer distinct advantages, allowing manufacturers to select the best option based on application needs and environmental factors.
