Understanding Kilovolts & Microamps and How Are They Used in Powder Coating?

by | Thursday, August 15, 2024 |

Importance of Electrostatic Charge in Powder Coating The electrostatic charge is a core component of the powder coating process. It is used to transfer the powder coating to a grounded part to hold the powder in place for the curing process. The electrostatic charge is typically applied using a spray gun that can adjust the electrical voltage (measured in kilovolts, or KV) and in some systems the current (measured in microamps, or µA) as well. This charge (known as a corona field) is how the...

Unlocking the Magic of Dormant / Illusion Powder Coatings

by | Thursday, August 8, 2024 |

Dormant powder coatings, also known as illusion powders, offer a unique visual effect that transforms before your eyes. Initially, they appear as a dull, metallic finish, but with the application of a clear top coat, their true color and effect emerge, revealing a deep, rich, multi-dimensional finish. How it Works The process involves an initial layer of dormant powder, followed by a clear coat that activates the underlying colors and effects, creating a stunning visual transformation. By...
