Copper and Copper-Alloy Chromates
Luster-On Cobra C:
A liquid chromate that produces bright attractive surfaces on brass or copper in a single dip operation. It is particularly attractive because of its nonfuming characteristics and for the exceptional shelf life of the treated products.
Luster-On NS:
A chromate coating for copper and copper alloys. It is used to retard tarnishing, and in many cases has prevented spotting out. The material can be used on buffed copper and brass surfaces and thin electroplated brass and copper deposits without destroying the luster.
Luster-On 70: This powdered chromate material is formulated to produce lustrous finishes on copper and copper alloys and provides protection against
staining, tarnishing and corrosion. Luster-On 70 coatings exhibit excellent paint bonding qualities.
