Iridite - RoHS compliant version of yellow chromate?

(-----) 2006

Since July 1st we now need to receive only RoHS compliant stock. Most of the 19" rack or slice panels, designed for our cable assemblies, were originally specified with a yellow chromate finish on steel. One of our suppliers is now asking if they can use Iridite. Is this RoHS compliant and how does it differ from standard yellow chromate?

Our customers require that we verify/certify that the products we sell are RoHS compliant.To do so, we verify with our suppliers that their products are compliant. I would recommend against telling your supplier that a particular product/coating is OK, as you then accept liability.

Ask your supplier to furnish you with an acceptable product that is RoHS compliant. Let them do what you are paying them for. RoHS compliance isn't exactly new.

Iridite* is a chemical name like Alodine*, no different from your standard yellow chromate.
Both products are chemical conversion chemicals containing Hexavalent chrome, a RoHS prohibited metal.

Iridite is a brand name and comes in many different types. Some of these are RoHS compliant, some are not. Better ask your supplier about the exact product they are using. You can then request the information from the manufacturers as to whether the product is RoHS compliant.
Iridite is a Macdermid product, so either check out their website or just phone them up.
