Powder Coating for Electrical Enclosures
Enclosures, switchgear and control boxes need corrosion protection, precise edge coverage and finishes that keep fits and grounding reliable in industrial environments.
Recommended Coating Systems
- Polyester or hybrid for indoor cabinets
- Epoxy systems for aggressive environments
- Fine texture for shop-floor products
Key Performance Properties
- Edge coverage on punched sheet metal
- Corrosion resistance for C3–C5 classes
- Consistent film for door and seal fit
- Good insulation properties
Typical Specifications
- Film thickness: 60–120 µm (typical)
- Gloss: textured or matte
- Cure: 160–200°C
- Salt spray per corrosivity class
Application Notes
- Mask threads, grounding points and vents
- Control film at edges and holes
- Verify door and seal fit after coating
Frequently Asked Questions
Does coating affect grounding?
Grounding points can be masked or pre-drilled — just specify them in advance.
What thickness suits outdoor cabinets?
80–120 µm with corrosion-class testing is typical for outdoor enclosures.
Buyer Decision Snapshot
Define masking, grounding points, UV exposure and IP/testing requirements early.
