At Great Dane’s new electrocoating facility, we immerse metal parts in a water-based solution where an electric charge causes a paint or resin emulsion to condense on the part.
The result is a protective coating with: superior corrosion resistance, a uniform, even coat, and extended part life.
What about masking? Just as with powder coating, masking may be necessary to prevent certain areas of a part, like threads or grounding surfaces, from being coated.
Electrocoating (also called e-coating) is great for parts with complex shapes, but those same parts may have challenging masking requirements. Mistakes in electrocoating can cause a production run to be started over, including stripping the old e-coat off the part.
Because e-coating takes place in an aqueous solution, special care must be taken if masking is necessary. Water, after all, is good at finding a way in to almost anything.
Finally, since e-coats cure in an oven at temperatures similar to powder coating, all masking materials must withstand these temperatures too.
As you can see, electrocoating requires an experienced team. The advantages of the immersion process come with challenges that, if not addressed with the proper techniques, can ruin the job.
Electrocoating is a unique process, one in which the thickness of the protective film can be precisely controlled. Not all parts, even ones with threads, tight tolerances, and grounding surfaces, need to be masked.
It’s possible to forego masking under certain circumstances, including:
