Definitions
- the term "satisfactory deposit quality” means a zinc deposit that :
- a bath was prepared containing :
- Example A The plating conditions of Example A was maintained but with a current of 5 amps and a temperature of 45°C.
- Example B was repeated, but heliotropine replaced with polyethylene imine G35 (BASF) 6 g / l .
- BASF polyethylene imine G35
- the example 3 was repeated, but with the G35 replaced with poly quaternary amino additives.
- deposition rates can be futher enhanced by increasing concentration of both alkali metal hydroxide and zinc in solution.
- Additions of soluble silicates to the electrolyte have a small but significant effect in improving brightness in combination with other additives under conditions of increased current density.
- Actual rates of deposition for satisfactory quality for a given electrolyte at a fixed temperature are critically dependent upon agitation, more specifically, the rate of mass transfer at the cathode.
