METALAST Aluminum Anodizing Chemistry

The two-step electrolytic coloring process applies an alternating current at 15-20 volts to deposit metal into the unsealed (open) pores, which provides the color. Metals typically deposited by this method include tin, copper, silver and molybdenum. The intensity of color depends on the time of exposure. It is important in this coloring process to avoid all agitation; eductors are appropriate.

METALAST®- TrueColor 5000 - Tin based electrolytic color product that produces superior lightfast colors from champagne to black on anodized aluminum. Use at 9-100% v/v with 0.8-1.1% Truecolor 5001 and 18-20 g/L sulfuric acid at room temperature. Coloring voltage and time are dependent upon the alloy, oxide thickness, and desired color.
