Wet Painting

Any color, any gloss, any substrate: the flexible coat for plastics and appearance prototypes.

Process specifications

Parameter	Value
Process group	Coatings & Painting
Coating thickness	20–60 µm
Tolerance impact	Moderate: adds 20–60 µm per surface with some variation at edges and recesses. Thin enough to ignore on most cosmetic parts, but mask toleranced fits, threads and datum faces — masking is routine and cheaper than rework.
Corrosion rating	Moderate and paint-system dependent — two-component polyurethane and epoxy primers reach hundreds of salt-spray hours; single-coat decorative systems are cosmetic protection only.
Appearance	Any color matched to Pantone or RAL at any gloss level from dead matte to high gloss; soft-touch and textured options available — the finish of choice when a machined prototype must look like the molded product.

⚠ Not suitable for

High-wear sliding surfaces — paint abrades and chips under repeated contact (use hardcoat, ENP or PTFE there); long outdoor structural service where powder coating outlasts it at similar cost; surfaces requiring electrical conductivity or grounding; fuel and solvent contact unless a rated paint system is specified.
