Brightener for galvanic coatings ZINK BSC-A application
Brightener Zinc BSK-A you can buy in Kharkov in the Internet-shop of chemical agents Novhim.
It is a new highly effective glitter-forming additive for weakly acidic zinc electrolytes.
Advantages of using Zinc BSC-A:
- It is used as an independent component.
- BSC-A produces a semi-glossy zinc coating
- Guarantees corrosion resistance
- Combined with BSC-B produces a bright zinc finish.
- The presence of ZINK BSC-A extends the zone of high current density on the coating.
- Provides a plastic even coating on all parts of products, with configurations of any complexity, including the inner sides of holes and recesses.
- Eliminates the appearance of the burns and stabilizes the electrolyte.
Instructions for use:
To get a reliable coating, it is sufficient to inject the offered glossing agent in an amount of 30-50 ml/liter. Recommended current density in this case is 0,1-8 A̸ .
Recommended electrolyte composition for weakly acid basic galvanizing
Zinc chloride – 30-50 g ̸/l
Potassium chloride – 150-200 g ̸ l
Boric acid – 30 g ̸ l
ZINK BSC-1 glossing agent – 30-50 g ̸ l
To get a mirror shine of zinc coating, the additive BSC-B can be used simultaneously with BSC-A.
Why it is better to use additives BSC-B and BSC-A at the same time:
- Increases the scattering ability of the electrolyte
- Uniform distribution of zinc layer thickness on all parts of complex-shaped parts is improved.
- A combination of BSC-A and BSC-B is most effective when galvanizing in drums.
- Total consumption rate of the two-component additive is considerably lower than that of the one-component additive.
Comparison of BSC-A and BSC-B with imported analogues represented at the market of Ukraine showed that their consumption does not exceed the consumption of their foreign counterparts.
BSC-A can also be used in electrolytes with ammonium chloride and is compatible with German and another additives available at the Ukrainian market.
Brightener Zinc BSK-A you can buy from the warehouse of Novohim Company in Kharkov or with delivery in Kiev, Dnepr, Zaporozhye, Poltava, Sumy, Kherson and all over Ukraine.
