Steel bridges, vehicles or even fences are generally outside in a moist, humid and sometimes even harsher environments and should therefore be treated to prevent rust as much as possibe. Galvanising or even organic coatings can prevent oxygen, water, salts and metal from coming together at the substrate surface. Because if this is prevented, corrosion can also be delayed as long as possible. However, this requires a closed film and good adhesion to the metal. This is relatively easy to achieve with solvent-based systems from solution. Aqueous binders with their discrete binder ...
