Electrostatics is a branch of physics that studies the phenomena and properties of stationary or slow-moving electric charges (Electrostatics, 2016). Electrostatic phenomena is easily demonstrated when lint is attracted to clothes, or when dust clings to a TV screen. These descriptions are examples of Coulomb’s law. Coulomb’s law states that opposite electrical charges attract and like charges repel. Electrostatic spraying has been used for many decades in painting and agriculture.
EMist uses this same process to apply a charge to the liquid droplets as they are formed and just before the droplets leave the spray nozzle. These “super-charged” droplets then actively seek out negative or neutral surfaces. What’s more, as the droplets leave the nozzle, the charged droplets repel one another, keeping them from coming together and forming larger droplets. Interestingly, because of the electrostatic charge, droplets “wrap” around surfaces providing an even, consistent surface coverage.
