Powder Coating
IN DEPTHAlso: Powder coat, electrostatic powder coating
A dry powder sprayed electrostatically and oven-cured into a tough, solvent-free finish.
How it works
Powder coating applies a dry powder made of resin and pigment. The powder is given an electrostatic charge and sprayed onto the grounded metal part, where it clings. The part then goes through an oven where the powder melts and cures into a continuous solid film. There are no liquid solvents, which makes the process cleaner than liquid painting.
Why it suits drinkware
The cured film is thicker and more durable than a typical liquid paint layer, so it resists chips, scratches, and daily handling better. It is the finish responsible for the soft, slightly textured grip feel on most modern bottles. Buyers often specify it because it survives shipping and rough use well.
Powder coating vs alternatives
| Finish | Thickness | Durability | Typical use |
|---|---|---|---|
| Powder coating | Thicker film | High, chip-resistant | Colored bottle bodies, grip feel |
| Liquid spray paint | Thinner film | Moderate, can chip sooner | Gradients and fine detail |
| PVD | Very thin, metallic | Highest, hardest | Metallic and gradient effects |
Color and texture also matter. Powder coating can be formulated in a wide range of solid colors and surface textures, from smooth to a fine grain. It holds color well, though very dark or very bright shades should still be checked for dishwasher and UV fading as part of your own testing.
The tradeoff is mostly about flexibility and color range. Powder coating excels at solid, durable colors, but liquid paint and PVD are better when the design needs fine gradients or a true metallic look. Choose the finish against how the bottle will actually be used and shipped.
Practical takeaway: Specify powder coating for solid-color, high-wear bottles and reserve liquid paint or PVD for designs that genuinely need gradients or metallic effects.
