Guide to 2-Step Anodizing vs. Integral Color (Discontinued)
Because of certain performance advantages, SAF now offers the more generally accepted 2-step anodizing process. We no longer offer the Integral Color, aka Duranodic, anodizing process.
Below are some key differences between the two anodizing processes, especially for architectural aluminum finishing applications:
2-Step anodizing
- Does not craze when fabricated as badly as Integral
- Color is independent of coating thickness
- In general, more anodizers use the 2-step process
Integral Color (Duranodic) DISCONTINUED
- Harder coat (more dense) than 2-step
- Generally a thicker coat than 2-step unless Class I 2-step is specified
- Single step process
- Hides welds a little better than 2-step
