🎨 A Classic in Protection: Total Insulation
Painting is probably the best-known protective treatment, but that does not make it any less technological. Like cataphoresis, its primary function is to create a physical barrier that completely isolates the steel from external agents (moisture, chemicals, oxygen), preventing the onset of corrosion.
💧 Liquid vs ❄️ Powder: Two Technologies Compared
There is no single type of painting; depending on the technical and aesthetic needs of the item, we choose between two main methods:
- 1. Powder Coating: Paint particles are electrostatically charged and sprayed onto the part, which is then “cured” in an oven.
Advantages: Great mechanical resistance, uniform thickness, and solvent-free.
Ideal for: Components requiring a robust and durable coating.
- 2. Liquid Painting: The paint is atomized onto the surface using spray guns.
Advantages: Possibility of achieving thinner layers, extremely high-gloss finishes, and applicability to components that cannot withstand high oven temperatures.
Ideal for: Products with complex geometries or where aesthetic appearance is a priority.
🔩 Threads and Thickness: The Technical Challenge
A crucial aspect to consider in industrial painting is the significant thickness the coating can reach. While this guarantees excellent protection, it can create functional issues:
- Thread Protection: On technical items like those produced by Zarri, threads are often protected (masked) before treatment. This prevents paint from building up in the thread crests, which would make it impossible to screw on nuts or bolts later.
- Tolerances: It is essential to account for the paint’s thickness during the design phase to ensure correct final assembly.
