Painting Surface Treatment
Painting is a common surface finishing process used on parts to protect them from corrosion and environmental forces. It is often used as a cosmetic finish for external parts. There are multiple painting methods used for part surface finishing. Some of the popular methods are, spray painting, electrostatic painting, brushing, and dipping.
Paints have a broad range of varieties that have special properties and aesthetics. Different paints can provide greater protection from specific environments that the part is made for. For precise and uniform painting, automated systems can be utilized. Prolean offers a large range of paints for manufactured parts.

Specify the environment, preparation and film performance as one system
A paint requirement should connect exposure environment to substrate preparation, primer/topcoat system, color/gloss, dry-film data, cure constraints, masking and the inspection or test evidence required for the finished part.
Engineering data to lock before release
| Exposure basis | Indoor/outdoor, corrosion category and service media |
|---|---|
| Preparation | Surface condition and pretreatment requirement |
| Paint system | Primer/topcoat, color, gloss and film data |
| Acceptance | Visual standard, film measurement and performance test |
ISO 12944 guidance is system-based: environment, preparation, coating selection and inspection should be considered together.
