INTERACTIVIA Black E-CRO Aluminum Anodizing Dye — Professional Black Shade, 7.6 L Yield

Overview

INTERACTIVIA Black E-CRO is a professional anodizing dye formulated for aluminum and compatible metals. The resulting shade can range from light gray to deep black depending on the duration of the anodizing bath and the dye bath, giving you versatile color options for metal finishes.

Why designers and fabricators choose Black E-CRO

• Creates a durable, thick oxide layer that enhances hardness, scratch resistance, and corrosion protection.
• The porous oxide accepts vibrant color while delivering repeatable, consistent results across batches.
• RoHS compliant and produced in the USA, packaged for long shelf life when stored properly.

Activation and usage

Each 80 mL bottle contains powder to make about 7.6 liters (2 gallons) of dye bath. To activate, open the canister, fill with distilled water to about 12 mm from the opening, close tightly, and shake for 30 seconds. After activation, use the product within one year. Maintain dye bath temperature between 120 and 140 °F and keep the pH in the range of 5.0 to 6.0 for best results. The dye shows fast uptake and color depth depends on the anodizing cycle and saturation level.

Color control and practical tips

• Color depth varies with the anodizing duration; test on sacrificial samples to dial in the shade you want.
• Consider post-dye topcoats or protective finishes to further enhance durability.

Safety and storage

Read the SDS prior to handling. Avoid inhalation, ingestion, eye contact, and skin contact. Store in a cool, dry location away from children. The dye is packaged in a UV protective bottle to preserve shelf life and is RoHS compliant.

Notes

Anodizing is an electrochemical process that forms a thick oxide layer on aluminum, enabling a range of color outcomes. Black E-CRO is designed for professional use and is intended for aluminum and specified metals only. The final shade is influenced by process parameters and dye bath duration.
