Use of I-Line XA-20 passivation agent
Caramba I-Line XA-20 passivation agent is an aqueous corrosion inhibitor for cast iron and steel in immersion and spray procedures.
Slowly add the required quantity of CARAMBA I-Line XA-20 passivation agent to the bath formulation while stirring. Observe the recommended dosage, treatment temperature and treatment time (see “Technical data”). The passivation effect can be enhanced by using deionised (DI) water instead of tap water. For bath monitoring and if an additional dose is required, we recommend checking the effectiveness in the grey cast iron swarf test according to DIN 51360-2.
Caution: Discolouration of the workpiece may occur when using non-ferrous metals if the treatment time exceeds the maximum recommended time.
