Powder Coating
WE ONLY SELL NORDSON POWDER COATING EQUIPMENT
Powder Coating is a protective finish which is applied as an electrostaticly charged free-flowing powder. The main differences between a conventional liquid paint and powder coating is that the powder coating must be melted or cured after application, and powder coating does not require solvent to keep the protective coating in a liquid suspension during application.
- Advantages: Powder coatings emit zero or near zero volatile organic compounds. Powder coating overspray can be recycled and thus it is possible to achieve nearly 100% use of the coating. Powder coating usually yields a part with a thicker protective coating layer and better performance.
- Limitations: Initial capital equipment costs of powder coating equipment is far greater than a liquid spray system. Coating requires a cure oven to crosslink the powder particles. Proper part surface preparation is critical to coating adhesion and performance. It is difficult or impossible to cure parts that cannot handle the high temperatures (300-400 degrees F) generated during powder curing process.
