We're asked this question regularly — often by customers who have received one quote for powder coating and one for wet spray, and aren't sure which result they'd actually prefer. The honest answer is that neither technology is universally better. But for the vast majority of metal components in industrial and architectural applications, powder coating wins on almost every meaningful dimension.
The Fundamental Difference Liquid paint is a solution of pigments, resins, and binders dissolved or suspended in a solvent (water or organic solvent). That solvent is what makes it sprayable; it evaporates during and after application, leaving the dried paint film behind. The film is formed by solvent evaporation and, in two-pack systems, chemical cross-linking. Powder coating is a 100% solid system — no solvent, no liquid carrier. Dry polymer particles are applied electrostatically, then melted and chemically cross-linked in a curing oven. The film is formed entirely by heat-driven polymerisation, not evaporation. This single difference — solid vs. solvent-borne — drives most of the performance and environmental distinctions between the two technologies.
