## Overview

Black E-CRO is a professional-grade anodizing dye powder that activates into 7.6 liters of rich black dye bath. Designed for aluminum and select metals, it offers fast uptake, consistent color results, and a long shelf life thanks to its UV-protected packaging. RoHS compliant and made in the USA, this dye enables precise control over shade intensity from light grey to deep black, enhancing durability and corrosion resistance of anodized surfaces.

## Description

READ SDS SHEET PRIOR TO HANDELING AVOID INHALATION, INGESTION, EYE AND SKIN CONTACT KEEP OUT OF REACH OF CHILDREN Deep Black - Black E-CRO is an anodizing dye. 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 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.

## Features

## Questions & Answers

**Q: why does black cost twice as much as any other color?**
A: Black dye is more complex to make. 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.
