Multimetal coating (steel-aluminium)

After years of testing and experimentation, the patented Soft Rain system offers significant advantages in the paint industry:

  • Reliability
  • High performance
  • Consistency over time
  • Low environmental impact

What happens without the Soft Rain system

In a normal pre-treatment tunnel (with an acid bath at 45 ° C at the head), the current process, without final passivation, achieves a result of about 150 – 200 hours in a neutral salt spray chamber. With effects, in addition, discontinuous due to entrainment.

What happens when you choose the Soft Rain system

Same pre-treatment tunnel, but to which is added the nanotechnological passivation and, in combination, the Soft Rain technology. The results, tested, are considerably superior: a final quality between 800 and 1200 hours in a neutral salt spray chamber. All this, with low management costs and reduced environmental impact due to the absence of wastewater and the high automation of the entire procedure. Furthermore, unlike the situation described above, the results are constant and certain over time since the risk of contact with any dragging has been completely eliminated.


Even in the galvanizing sector, as for painting, Soft Rain can lead to considerable advantages:

  • Cost-effective
  • Organizational and management
  • Environmental

What happens without the Soft Rain system

In the galvanizing sector, a very widespread situation is where there is a traditional passivation process that dedicates a single tank to the immersion of the supports to be treated. In this situation, however, there are several critical issues: from the harmfulness of the passivating solution, to the risk of pollution in the tank itself, to the prolonged duration of the drying phase, etc.

What happens when you choose the Soft Rain system

By introducing Soft Rain technology, on the contrary, it is possible to eliminate several problems and obtain important benefits, including:

  • Faster passivation
  • Better quality of passivation, as it is no longer subject to pollutants
  • Optimization of the entire process, in terms of occupied spaces and produced waste
