Optimizing voltage settings for efficient powder coating is a critical step in achieving a uniform, durable, and high-quality finish while reducing overspray and power usage. Powder coating relies on electrostatic attraction to adhere electrostatically charged coating material to a conductive base material. The electrostatic potential set directly influences the intensity of the charge gradient, which in turn affects coating yield, uniformity, and layer density.

Setting the voltage too low may result in poor adhesion and uneven coverage, while Applying excessive charge can cause repulsive ionization, creating a bumpy, orange-peel surface or even particle ejection from the substrate.

To begin optimizing voltage, Tehran Poshesh first understand the distinctive attributes of your coating formulation. Different powder formulations have varying charge retention properties and particle sizes.
