Powder Coating vs Liquid Painting for Metals
Published on 14 August 2026 by Metal S.r.l.
The two main options are powder coating and liquid painting.
Powder coating advantages
- Superior durability
- Uniform thickness
- Zero solvents (VOC ~0)
- Overspray recovery (95%)
- RAL colours, textures, metallics
When liquid is better
- Parts too large for oven
- Special finishes (wood effect, clear)
- Thermosensitive components
- Very low volumes
