For corrosion resistance on unpainted surfaces without chromium Chemidize NCP is the choice. Chemidize NCP will provide salt spray resistance to rival conventional chromating and can also be used to provide a base for paint or other organic coatings. Chemidize NCP is not effected by high temperatures and no curing is required before painting.
The Iridite and Chemidize ranges of products will provide efficient pretreatment under paint, whether you need chrome or chrome free products. For multi-metal use where steel, aluminium and perhaps zinc have to be processed our Keykote I/M3 (a cleaner/iron phosphate) may be a better choice. Use the link above to find our range of pre-paint phosphate treatments and post phosphate adhesion enhancers.
MacDermid supply a comprehensive range of products to prepare aluminium for anodizing. Non-etch cleaners such as Minco or Alprep 230 will remove oils and general shop soils. Long life etches such as Aluminium Etch ELE will then provide a consistent quality of etch throughout their life. Following the etch with one of the Deox or Alprep range of nitric acid free deoxidizers/desmuts will ensure a clean, smut and oxide free surface ready to be anodized.
After the anodizing process our Fox AGA cold seal is a money saving, reliable way to seal the anodized coating. Fox AGA will save considerable amount of energy in comparison to using boiling water and, as the seal goes on working after the initial treatment, a full seal is always achieved.
