Use Black E-CRO only on aluminum, magnesium, titanium and tantalum. Most commonly, Black E-CRO is used on aluminum. It is not intended for use on any other metals or materials. Black E-CRO can change its shade of grey to black depending on how long it is in the anodizing bath and in the dye bath. It can be a light grey if you do a shorter anodizing cycle. For a longer duration in the anodizing bath and in the dye bath, it will look like dark black. The anodizing process parameters have a significant impact on the properties of the oxide formed. This means that the color is dependent on the anodizing process. Black E-CRO is RoHS (Restriction of Hazardous Substances) compliant. It is made with fume suppressants. Specifications on Black E-CRO Concentration - This 80 mL bottle contains 60 grams of powder to makes 7.6 L or 2 gallons. pH - 5.0 – 6.0 (Raise with ammonium hydroxide, lower with acetric acid.) Temperature - 120-140°F. Light Fastness - 7-8 Time - 4-10 minutes depending on saturation preference. Anodizing is an electrochemical conversion process. Anodizing changes the outer surface of the aluminum. Anodized aluminum has different characteristics than raw aluminum. Some of the characteristics of anodized aluminum include durability and weight. (It is lighter weight than stainless steel.) The process of “anodization” creates a thick oxide layer. This thick oxide layer makes it very hard, quite scratch resistant and improves its corrosion resistance. Also, the thick oxide layer makes it easier to clean than raw aluminum. Because of its porous nature, anodizing makes it possible to dye the aluminum many different colors. Store in a cool dry environment. ## Features - All instructions and key dye features are labeled on the bottle for easy reference, including a color swatch. - Packaged in a UV protective bottle to ensure a long and stable shelf-life of unused dye. - THIS DYE IS SHIPPED IN POWDER FORM TO INCREASE SHELF LIFE.

For example the red dye used 16 grams of material to make 2 gallons, where is this black dye uses 60 grams to make the same amount. **Q: How is it applied? Like you would apply a paint or stain or??? Thank you.** A: This is an anodizing dye. And dyes like this are absorbed into an anodized aluminum surface. First learn about anodizing before buying these dyes. It involves electricity, sulphuric acid and experience. Anodizing pits microscopic holes into the metal surface and this dye is the exact size to fit into those holes. Thus dying the metal. Search YouTube for how to Anodize aluminum. You'll find some videos there. Don't buy until you know how to Anodize! **Q: will this work on titanium?** A: No. Titanium anodizing is through electrical current and time. There are no dyes for titanium anodizing. I don't believe black is possible in titanium but I could be wrong. These dyes are exclusively engineered for aluminum anodizing. Thanks and good luck! **Q: Someone asked why the black costs more than the other,and was answered with"its more complex to make".Then why are other brands black cheaper?** A: All our colors consist of 16 grams of pigment to produce the 2 gallons of colourant. The black however requires 60 grams of pigment to produce the same. So it contains more than 3 times the pigment. These dyes are pure pigment. Other brands are mixed with a solution and thus not pure pigment powders. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Deep Permanent Dye *by on Reviewed in the United States January 19, 2026* This dye penetrated my anodized aluminum evenly and permanently. I should add a note for the curious: After diluting the powder in water and using it for my project I decided to save the liquid in a giant Mason jar, thinking I would use it again. One year later I located the jar in the back of a cabinet and discovered a healthy colony of mold growing on the surface. I disposed the entire contents of the jar so I can't report about the effectiveness of the dye. ### ⭐⭐⭐⭐⭐ I hate RIT dye *by on Reviewed in the United States September 29, 2023* RIT doesn't work. Don't do it. This is expensive but worth it. Don't waste time with RIT like I did. I ended up with gritty, splotchy, barely-dyed, reddish parts. I thought I was doing something wrong. I was. I was using RIT dye. After switching to this, my parts went from "I don't know what I'm doing" to "anodizing master". Don't make the mistake I did. ### ⭐⭐⭐⭐⭐ Amazing customer service! Partially filled red and blue bottles NORMAL! *by on Reviewed in the United States January 3, 2025* I ordered 3 bottles of these dyes, black, blue and red. I got the black first, used it and it worked perfectly! The bottle was full to the top.I then got the red and the bottle was almost empty. Me being a rookie anodizer, I didn't realize black takes more dye than the other colors so it's normal for the red and blue bottles to only have a teaspoon or so in them.I called Interactivia's customer service number that's listed in their profile and talked to a VERY helpful guy. He's done anodizing himself and not only answered my question on why the red and blue bottles were only partially filled, he gave me some awesome advice on the anodizing process.To have customer service like that is amazing these days. I REALLY appreciated the quick response to my phone call and having a helpful person on the other end.
