5. FAQ
Q1: What is ED coating and how is it applied?
A1: Electrophoretic deposition (ED or e-coating) is a dipping
process where a uniform film forms on electrically conductive
parts. It offers excellent coverage—even in cavities—and superior
adhesion.
Q2: How does ED coating compare to powder coating?
A2: ED coating is thinner and better for tight-tolerance
applications. It provides a highly uniform base and excellent
corrosion resistance but less UV resistance compared to top-coated
powder systems.
Q3: Can the ED coating color be customized?
A3: Yes, we can customize shades (typically in black, gray, or
silver ranges) to match OEM standards or Pantone references.
Q4: Are the coated enclosures paintable or laser-markable?
A4: Absolutely. ED-coated surfaces can be painted over, printed on,
or laser marked for branding or part tracking.
Q5: What standards do the coatings meet?
A5: Our ED coatings meet IATF 16949, RoHS, and ISO corrosion test
standards including salt spray, thermal cycling, and adhesion.
Q6: Can this coating be used in marine or chemical environments?
A6: Yes. ED coatings offer excellent base corrosion protection. For
marine or highly acidic environments, we recommend duplex coatings
with powder or topcoat layers.
