  2. This coating can be applied to zinc or cadmium alloys.
  3. After coating, the product can withstand up to 130 hours in a saturated salt spray without deteriorating its performance.
  4. This passivation contains an iron corrosion inhibitor and resists accumulation of zinc in the solution.
  5. The coatings are capable of withstanding a short-term heating to 250°C or a 24-hour stay in the temperature zone reaching 120°C.
  6. The concentration of cobalt in the proposed solution is not more than 1 g/l, besides the solution does not contain fluorine ions

Passivation of zinc coatings PAS-BCP instructions

In order to obtain a working solution, PAS-BCP concentrate is introduced into the bath, filled with the necessary amount of water, at a ratio of 25-40 ml/l. Then nitric acid is added at the ratio of 2-3 ml/l and the volume is brought up to the necessary working volume. After that, the solution is adjusted by bringing the composition at the rate of 10-15 g/m2. The pH is also adjusted, which should have values of 1.4-1.8 units.

The recommended temperature of the bath should be 18-30 ° C and the duration of the procedure should be 10-30 seconds.

At the end of the passivation process it is recommended to rinse the items for 30-60 seconds. First in cold water, then in warm water, but not exceeding 60°C.
