Interpon D2525 Anodic III Color Card
Tale of the Tape
| Anodising | Powder Coating | |
|---|---|---|
| Chemical Resistance | Very susceptible to acidic and alkali pollutants. Low resistance to mortar and iron oxide. Higher rate of erosion in highly industrial areas | Generally good resistance to acid, alkalis but care must be taken when using brick cleaners. Chlorinated hydrocarbons and ketones should be avoided |
| Finish Consistency | Difficult to control colour consistency between batches, heavy/light extrusions, extrusion vs sheet profiles. Standards allow for large colour variation | Colour consistency can be controlled using 1 batch of powder and consistent application method (automatic) |
| Fabrication | Welding joints are very difficult to anodise and creates significant colour variation. Curved panels also problematic | Good adherence and colour consistency on welds. Bare metal edges need to be sealed in hazardous environments |
| Environment | Acid intensive process. High energy consumption to maintain electrolytic tanks. High water usage. Cobalt classified as carcinogenic | Solvent free application process. No Volatile Organic Compounds (VOC’s) or heavy metals used in formulation. 95% recyclable during application |
| Substrate Cost | Aluminium grade must be of high quality as imperfections will otherwise be visible- Higher reject rates- added cost | Coating thicknesses of > 50microns enable substrate imperfections to be hidden |
| Repair | Once scratched anodising cannot easily be repaired | Powder coatings can be rectified using a primer and a 2 pack Polyurethane (PU) |
| Cost (3mm solid aluminium panel) | Can have significantly higher applied cost. Cost per m2 varies between £200-£400/m2. | Dependant on quality and shade. Typical applied cost of between £90-£130/m2 |
