A wet paint coating system is an industrial finishing process that applies liquid paint onto a product surface using spray guns, followed by drying or curing in a controlled environment; unlike powder coating, wet paint uses liquid coatings containing solvents or water, making it suitable for a wider range of materials, colors, and surface finish requirements, and is commonly used in industries requiring high cosmetic finishes, multi-color applications, large fabricated structures, or coatings with specialized properties such as chemical resistance, UV protection, or high-temperature performance; the typical wet paint coating process flow includes Material Loading, Surface Pre-Treatment, Dry-Off (optional), Paint Preparation & Mixing, Primer Application (optional), Flash-Off/Dwell Zone, Topcoat Application, Flash-Off/Masking Zone, Drying/Curing Oven/Ambient Drying, Cooling, and Surface Inspection & Unloading.
