Lanthanum is a chromium(VI)-free passivation for aluminum based on chromium(III) compounds and is free of nickel and cobalt. This passivation increases the corrosion protection of aluminum and can be used as a primer for lacquers and adhesives.
Meets all standards (ELV, RoHS and WEEE).
Contact resistance of the passive layer < 0.8 mOhm/cm² according to MIL-DTL-81706.
Depending on the aluminum alloy, a corrosion resistance of 96h – 500h according to DIN EN ISO 9227/NFA 05 109 can be achieved.
