The technology of decorative processing of parts surfaces uses galvanic glossy nickel plating and consequent application of anaphoretic colourless water-soluble varnish ALBRIFIN S, that can be coloured in such a way so as to reach appearance of brass (Ms), gold (Au), copper (Cu), black nickel (Ni) or some other transparent colour.
Brass plated fittings:
The following layers are then consequently applied to metal surface within technological process in one automatic line:
- basic metal – raw or mechanically treated (by grinding, blasting, polishing – depending on level of gloss required for the final appearance)
- pre-nickel plating – layer of 3 up to 10 microns
- glossy copper plating (acid) – layer of 14 up to 18 microns
- decorative nickel plating – layer of 4 up to 6 microns
- anaphoretic varnishing– layer of 6 up to 10 microns – colouring to required tint
- varnish baking at 150 up to 160 °C for the time of 30 minutes
The advantages of the technology are as follows:
- very good corrosion resistance of the galvanic base layer and decorative varnish
- excellent adhesion in cross hatch test according to ISO 2409 test
- keeping the tint in case of more component of one set
- very good resistance to sweat, cosmetics and chemicals (detergents, petrol, acetone, etc.)
- excellent resistance to abrasion – resistance to boiling water
- there are not developed drops and curtains
- the products are not touched by a human hand in the course of the whole processing – it is not necessary to re-hang parts
