Terra-ColorAL – process

Creative anodised shades in wood and earth hues

What is the Terra-ColorAL process?

The Terra-ColorAL Process is an electrolytic two-step colouring process for creating typical wood and earth shades subsequent to anodising. The process is similar to the conventional tin colouring technique and is achieved with the two-component product Alficolor 650 and Alficolor 651.
