Environmentally friendly, heavy metal-free color anodized dye

TAC DYESTUFF GR series

Environmentally friendly, heavy metal-free color anodized dye

Aluminum is widely used in electronic devices, smart phones, etc. because of its light weight, corrosion resistance, and strength.
Generally, organic dyes are used to color aluminum to improve its design and appearance. These dyes contain heavy metal ions such as chromium, iron, and nickel as complexes to stably bind dye molecules. In some conventional products, trivalent chromium has been used as a complex to improve light fastness and color stability.
We have now introduced a new heavy metal-free dye, TAC DYESTUFF GR series, as an environmentally and human friendly product.
