The electrocoating (e-coat) or cathodic electrodeposition is a painting method by dipping based on the displacement of charged particles in an electric field towards the pole of opposite sign. The translation in Spanish is cataforesis and in German is kataforetische lackierung (KTL).
Applying an electrical potential difference, paint molecules break and uniformly deposit on the workpiece (cathode) attracted to their charge.
The powder paint process is based on the electrostatic application of thermoset or thermoplastic dry paint that comes in the form of small particles.
The powder includes a large spectrum of colors, consistency, texture, hardness, flexibility, edge coverage, smoothness and temperature range of polymerization.
It is a combination technique, widespread in some industries like automotive, when there are large outdoor requirements.
The powder coating and electrocoating complement each other improving corrosion resistance, improving resistance to multi-impact stone chipping test, enabling the application of different colors and featuring (depending on the type of paint) a good resistance to ultraviolet rays
