02_ ANODISINg bY bwb THE ADVANTAgES OF ANODISINg
The BWB anodising procedures (electrolytic oxidation) combine the advantages of the electrochemically produced aluminium oxide layer with the aesthetic virtues of coloured aluminium in architecture and design. With the BWB anodising and colouration techniques, the aluminium retains its metallic nature. Corrosion resistance Anodising the aluminium produces a resilient and corrosionresistant protective layer. This ensures that components retain their value over decades. Colour retention With the BWB colouration techniques, the dye sits inside the pores of the anodised layer. Unique to the “Permalux” procedure, the colour effect is achieved by means of the integral layer structure. In the subsequent sealing process, all pores are closed. This results in extraordinarily high colourfastness. Light resistance The lightfastness of the dyes used is considerably higher than the highest value on the “Blue Scale” as per ISO 21352010 and complies with the EURAS guidelines. All colours exhibit excellent light resistance. Investment in the future The mechanical strength of anodised aluminium is very high. Even during slightly abrasive cleaning of the aluminium, the surface is not damaged. With proper maintenance, anodised aluminium parts retain their decorative value and metallic nature for decades. Ecology / recycling Comprehensive evaluation of economic and ecological aspects speaks in favour of the use of anodised aluminium as a material in architecture. Anodised aluminium also stands out due to lowemission colouration techniques, the high degree of recyclability and the very high stability of value.
