ELECTROSTATIC POWDER APPLICATORS
Terronics Electrostatic Powder Applicators are custom built to apply fine powders to non-complex continuous substrates in industries such as steel, paper, cosmetics, rubber, electronics, agriculture, medical, and food.
Most existing methods employ the powder gun as a means of charging and spraying the powder. While the gun may work well on small individual parts, it is ineffective when coating high speed, 2-dimensional continuous substrates.
TDC's powder applicators have either a brush or diffuser that aerates the powder past multiple charging electrodes that span the width of the target. Once the powder is charged, it becomes attracted to the target substrate where it is evenly distributed across the width. This system is far more efficient than multiple powder guns.

Understanding
Electrostatics
Electrostatics is the science interested in beneficially harnessing the many characteristics of electrostatic forces. The fundamental principle is based on mutual attraction of opposite electrical charges and mutual repulsion of like charges.
TDC's focus of applied electrostatics looks for creative ways to safely and effectively charge particles (liquid droplets or solid particles) so that they are attracted to intended targets and provide a high quality coating.​
​The principle behind this physics was applied first in the early 1900's in electrostatic precipitators to remove dust particles from smokestacks. Later it inspired the development of electrophoresis, powder paint sprayers, xerography, separation of metallic ore from tailings, and ink jet printers. But this subtle, yet powerful physics is far more useful than even these widespread applications. From what we have discovered at TDC, we know it has vast, yet-undiscovered potential.
