Optinox Pass

Passivation Solution

OPTINOX PASS: The surface of stainless steel materials is protected against corrosion, pitting, and rust by a thin passive layer rich in chromium oxide, which naturally forms on the surface under suitable conditions.

This passive layer forms only on clean surfaces containing sufficient chromium in the alloy and in environments containing sufficient oxygen. The resulting passive chromium oxide layer is self-repairing under normal conditions, even if the surface is subjected to mechanical damage.

Heat and mechanical processes such as welding, cutting, drilling, sawing, bending, drawing, and shaping damage this layer. This corrosion-resistant passive layer must be regenerated. Even the slightest contamination on the surface prevents the formation of this layer. The passive layer forms on surfaces that have been cleaned with pickling chemicals (OPTINOX B 100, B 200, B 300S) and have achieved a metallic shine.

Passivating stainless steel surfaces with OPTINOX PASS ensures the rapid formation of a corrosion-resistant passive layer.

INSTRUCTIONS FOR USE
OPTINOX PASS is applied to the surface by brushing, dipping, or spraying. The surface must be previously cleaned with OPTINOX SUFRACE, OPTINOX B 100, or OPTINOX and must have achieved a metallic shine.

At the end of the reaction period, the surface is washed with clean, high-pressure water (100-150 bar).

DOSAGE
Reaction Time: 30 minutes. Consumption: 10-15 m²/kg.
