With Bonderite M CR 1405 from Henkel, users can significantly shorten their processes when treating metal surfaces. As a so-called passivation pretreatment based on chromium III, the agent combines both processes.
Two process steps combined
Bonderite M CR 1405 can be used both as a passivation for bare substrates and as a pretreatment for painted substrates. It also has good recoatability. Passivated coils can be used in the coating line without a cleaning step and only require rinsing with hot water to remove impurities. This leads to considerable energy and water savings, as normally cleaners are used in large tanks at 60 to 70 degrees Celsius. By dispensing with chemical cleaning agents, the waste water is also significantly less polluted.
High corrosion protection
Bonderite M CR 1405 is chromium III-based. It offers a high level of corrosion protection and is also RoHS-compliant ("Restriction of certain Hazardous Substances"). This directive prohibits the use of hexavalent chromium in Europe. The test on galvanized and Galvalume substrates shows a bare corrosion resistance of more than 96 hours. The salt spray test shows a resistance of 800 hours with a chrome primer and 500 hours with a chrome-free primer.
