Products
Act preventively to better control the reappearance of rouging.
A Technochim solution developed to integrate rouging prevention into the maintenance of stainless steel installations.
Properties
01
Intervene in a planned manner before significant surface restoration becomes necessary again.
02
Integrate the treatment into a strategy aimed at preserving the restored surface condition and the properties of stainless steel.
03
Monitor surface evolution and adapt interventions to the actual behavior of the installation.
After restoration: protect.
Your need
After restoring a surface affected by rouging, the challenge is to maintain its condition and control its evolution over time.
PHOXAL is part of this preventive approach. Its use is defined according to the surface condition, the installation’s history, and its operating conditions.
Prevent • Protect • Maintain
Prevention & monitoring
The preventive use of PHOXAL presented here does not replace derouging when a surface requires restoration.
It intervenes with a different logic: acting on a restored surface and integrating its protection into the installation’s monitoring.
Diagnosis → Restoration if necessary → Prevention → Monitoring
This approach allows for a gradual shift from an essentially curative logic to preventive management of stainless steel surface conditions.
Rouging results from the evolution of the stainless steel surface under the influence of numerous parameters related to the installation, fluid, temperature, surface condition, and operating conditions.
PHOXAL should therefore be considered a prevention tool integrated into a monitoring strategy, and not as a guarantee of permanent absence of rouging.
The history of observations and interventions allows for gradually adapting the periodicity to the actual behavior of the equipment.

Technochim expertise
PHOXAL is part of the expertise developed by Technochim around the passive layer, rouging, derouging, and restoration of stainless steel surfaces.
Performance relies not only on the product but also on understanding the installation and the evolution of its surface:
Surface → History → Operating Conditions → Prevention → Monitoring
Preserve surfaces, monitor their evolution, and adapt prevention.
Technochim supports its clients in integrating PHOXAL into a maintenance strategy consistent with the actual condition of their installations.
