51W Window System : Finishes : Permanodic®


Kawneer Permanodic® is a range of subtle co-ordinated colours which have been researched and developed for architectural systems. The performance finish of all Kawneer products is assured as a result of a single source responsibility.
Permanodic® is a well tried colour anodising process, proven in accelerated laboratory tests, extensive field trials and contract experience, which gives architects and specifiers product confidence.
  • Permanodic® is available in five standard colour tones – Natural, Black and three Bronze options.
  • Permanodic® II is available as a steel blue-grey colour.
  • Permanodic® C is available in a range of blues, reds, turquoises and greens.
Various Kawneer Permanodic® colour finishes are available on all Kawneer aluminium systems and offer many exciting possibilities in colour contrast and harmony.
Permanodic® colours are achieved by colouring the anodic film resulting in a stable attractive finish with rich colour tones. The aluminium is immersed in specific electrolytes and subjected to stringent process controls, to produce a hard coating which forms an extremely durable protective surface which is fade free.
Permanodic® II colour is achieved by interference colouring produced by enlarging the anodic pores and depositing nickel metal in the base. By this method a steel blue-grey colour is produced which is fade free.
Permanodic® C is a combination method of over dyeing Permanodic bronze shades with lightfast organic dye stuffs which produce a range of subtle colours that are fade resistant.
