Product Description

Best Quality Petroleum Additives

1. Characteristics

(1) High stability, permits to work continuously for 10-30 days without any big treatment, produces nickel coatings with satin surfaces and consistent appearance.

(2) Uneasy to form bright and dark spots. Particle size is adjustable and easy to control.

(3) Fined and delicate appearance with strong metal feeling. The coating surface has good scratch resistance due to a hardness of 400-500 HV and is not easy to blister or peel off.

(4) Suitable for high-class hardware and plastics, such as mobile phones, automotive applications, bathroom products, leatherware, and electrical appliances.

3. Preparation

(1) Fill the tank with water to 1/2 of the volume, and heat to 60 °C.

(2) Add nickel sulfate, nickel chloride, and boric acid while stirring well.

(3) Add H2O2 0.5-1 ml/L and stir for 1 hour at 60 °C.

(4) Add 1-3 g/L activated carbon, stir for several hours, and let stand overnight.

(5) Filter the solution to get a clear liquid and pump it to the tank.

(6) Fill up with water to a required volume, dummy plate at low current for 12 h or until the color of dummy board changes from dark to light, and then adjust the pH to about 4.2.

(7) Add TNC-860A and TNC-860B.

(8) Dilute TNC-860C pearling agent with warm water 10 times and add it to the tank. Plate after agitation for 10 minutes.

4. Maintenance

(1) Roles of additives

TNC-860A Makeup: makes a uniform satin appearance at high and low current density areas, produces luster, reduces internal stress, improves ductility, and promotes mattness. Its overdose causes rough surface and pinholes. It is easy adsorbed by activated carbon.

TNC-860B Assistant: eliminates the formation of bright spots and pinholes, adjusts the fineness of surface. Its overdose causes rough surface. If insufficient, the satin coating is thin and even difficult to be formed. It is easy to be adsorbed by activated carbon.

TNC-860C Pearling agent: The increase of its concentration improves satin appearance and makes different effectiveness. It car be adsorbed easily by activated carbon, cotton cores, and filter papers, but only completely by activated carbon. It should be diluted with warm water by 10 times previously and added to tank slowly to improve its dispersion and prolong its service life.

(2) Consumption rates of additives

TNC-860A Makeup	120-150mL/KA.H
TNC-860B Assistant	120-150mL/KA.H
TNC-860C Pearling agent	130-160mL/KA. H
