The following types of equipment are used in the application of various types of coatings. Electrostatic Spray Rotary Atomization Dip Coating Summary Dip coating refers to immersing a piece into a tank containing the coating material, removing the piece from the tank, and allowing it to drain. The coated piece can then be dried by force-drying or baking. Dipping is extremely dependent on the viscosity of the paint, is very messy, and may be highly hazardous. The viscosity of the paint in a dip tank must remain practically constant if the deposited film quality is to remain high.
Dip coating is well suited for high production painting of relatively simple shapes.
Transfer efficiency is very high, all contact areas are coated, equipment requirements are low, and the process can be conveyorized and automated. The process is generally used to apply primers, not topcoats. A flammable paint can constitute a major fire hazard. An efficient fire-extinguishing system must be installed as a safety measure. Paint drippage from parts exiting the dip tank creates a mess that adds to the fire hazard.
