Powder Coating for Automotive Parts

From filters and brake components to wheels and fuel tanks, powder coating gives automotive parts the impact, chemical and corrosion resistance they need — with the thickness control precision fits require.

Recommended Coating Systems

• Polyester for exterior and visible parts
• Epoxy for under-hood and fuel-adjacent components
• Hybrids for cost-sensitive high-volume parts

Key Performance Properties

• Impact and chip resistance
• Fuel, oil and salt spray resistance
• Excellent edge coverage on punched parts
• Consistent film for tight fits

Typical Specifications

• Film thickness: 60–120 µm (typical)
• Cure: 160–200°C
• Gloss: per part specification
• Salt spray: 240–1000 hours on request

Application Notes

• Mask threads and mating surfaces
• Verify heat limits of rubber or plastic inserts
• Test adhesion on the actual production substrate

Frequently Asked Questions

Do the coatings resist brake fluid and fuel?

Epoxy and selected polyester systems pass fuel and brake fluid exposure tests.

Can you coat wheels?

Yes — with impact-tested formulations matched to wheel specifications.
