Conventional and Interference Electrocolouring

Conventional and interference electrocolouring are advanced techniques used to impart durable, aesthetically appealing colors to anodized aluminum surfaces.

– Conventional electrocolouring employs an electrolytic process to deposit metallic salts – such as Tin, Nickel, Copper, Cobalt, and Selenium – into the anodized layer, producing rich, long-lasting colors with excellent UV and corrosion resistance.
– Interference electrocolouring manipulates the oxide layer thickness to create vibrant, iridescent hues, offering a wider color spectrum inspired by optical interference effects.

At Cisart, we engineer and manufacture high-precision electrocolouring systems that are among the very few capable of maintaining strict production parameters within tight tolerances, especially in two-step interference colouring processes. This ensures exceptional color consistency, durability, and surface protection, making our systems ideal for architectural, consumer, and automotive applications.

By choosing Cisart’s electrocolouring technology, manufacturers achieve customized, high-performance anodized finishes, combining aesthetic excellence with superior material protection.
