The Perfect E-Coating Solution for You!
If you are considering high performing e-coating technologies, then you need Natec. More than 50 manufacturers around the world use Natec e-coating technologies both as beautiful one-coat solution, and as a high performing primer coat.
Remarkable Electrodeposition Paint
Typical paint lines run just one or a small number of parts through their process at any given time. The electrocoating process allows as many pieces as there is room to dip or immerse, at the same time. This varies according to the size of the tank, the amount of space you have to hang the parts and the number of anodes. That being said, as long as the pieces are not touching and are kept separate, you can fill the entire tank all at one time with proper setup

Why E-Coating?
Companies and individuals that use electrocoating do so because it stands up to the elements of the outdoors such as wind, rain and sun better than other types of coating processes. You will also see many examples of electrocoating indoors; in laundry areas and kitchens where harsh chemicals and detergents are present, electrocoated surfaces wear very well. In other words, electrocoating provides superior resistance to corrosion and protection to the pieces that have gone through the process.
Many manufacturers choose electrocoating to give their products a lasting finish that is both durable and cost effective. Though it costs a little more to set up the electrocoating lines, the fact that almost all of the paint is reclaimed, typically 97 to 98 percent, saves a lot of money over the long term.
Electrocoating is one of the most environmentally friendly paint line options. This is because of the fact that the electrocoating process creates almost no hazardous air pollutants (HAPS) or volatile organic compounds (VOCS). The electrocoating process is also compliant with OSHA, EPA and RoHS regulations, making it the most environmentally friendly coating process.

What is E-Coating?
Wise manufacturers choose the electrocoating process to give products a strong and tough finish that will last. E-coating is used globally to attain high-quality finishes that are cost effective and environmentally friendly.
Electrocoating is the process of applying paint to a metal surface through an immersion or dipping of the pieces which you want to protect. This process is called paint deposition and includes using an electrical current to make the paint particles, in a fluid bath, attract and attach to the metal surface of the piece during immersion. While electrocoating may have a higher initial cost, the benefits far outweight the initial investments in the long run.
Manufacturing Process
The parts are transported through the system, hung from a continuous moving monorail. Alternatively, programmed hoists or similar indexing devices are used to move the parts from stage to stage and in and out of tanks. The type of transport method is dependent on the part size, type and coated surface area requirement per minute. Natec offers consulting solutions for setting up fully automated manufacturing processes for e-coating.
How does it work?
Pretreatment
E-Coating
Rinsing
Baking
Parts are cleaned and pretreated with a conversion coating to
prepare the part for electrocoating.
Direct current is applied between the parts and a "counter"
electrode. Paint is attracted by the electric field to the part where
it is deposited.
Parts are rinsed to reclaim undeposited paint solids.
Paint is thermally cross-linked or cured.
