Economical trivalent blue passivation for use over zinc electroplated deposits. Operates at a low product concentration with high tolerance to trace impurities. Provides minimal corrosion resistance and does not contain cobalt.
-
COLDIP® TRI-V 120
Trivalent blue passivation for use over zinc electroplated deposits needing medium to high corrosion resistance. Flexible operation allows for adjustable immersion time and product concentration. This product contains cobalt.
-
COLDIP® TRI-V 121
Trivalent blue passivation for use over zinc electroplated deposits. Suggested for high corrosion resistance requirements where an additional sealer or topcoat may not be used. This product contains cobalt.
-
COLDIP® TRI-V 200 UB
“Ultra-Blue” trivalent passivation for use over zinc electroplated deposits. Provides high corrosion resistance and color intensity on acid or alkaline zinc deposits. Flexible operation allows for use in a wide variety of plating installations.
-
COLDIP® MIDNIGHT 1500
Latest generation trivalent black passivate for zinc plating. Easy-to-use process with a simple three-part system which allows for maximum color control and provides a consistent black appearance. The passivate works well over alkaline cyanide-free zinc and zinc-iron/cobalt alloy deposits.
