Hello!
Could anyone explain simply the principles and benefits of electrostatically applied marine coatings?

Hello,
roughly is based on the electrostatic attraction of electrically charged atomized
particles (either dry powder or liquid paint droplets) to the grounded (having earth potential) workpiece.
The charged particles coming out from the gun hit the whole surface of the object including the back surface therefore the electrostatic spray technique is mainly used for inside coating of tubular objects where the back surface painting (wraparound effect) is negligible.
Due to electrostatic effects the coating is thicker on the surfaces of protruding corners and thinner on inside corners and holes.
Electrostatic spray is characterized by very low overspray and utilizes at least 95% of the paint.
