Product features



Fast light speed


In a wide range of current density,
it can quickly obtain a mirror-bright coating, which is not easy to
produce pinholes and pits, and can
meet the requirements of obtaining
a high-bright coating in a short time





Strong filling ability

The coating fill level is up to 75%,

and the current density range is wide

Acid copper plating with high

brightness can be obtained not only

in high and medium current areas,

but also in very low current areas

Wide operating

temperature range

Bright and uniform copper plating

can be obtained in the temperature

range of 20-35℃

When the bath temperature is high,

the brightness will not be

significantly reduced in the low current area

Can reduce the defect rate and save costs





Low internal stress,

good ductility

The coating has good ductility, low internal stress, good adhesion to

the nickel layer, and is suitable for

ABS plastic plating


Fast deposition



The current efficiency is as high as 99%

or more. At a current density of

4.5A/dm², a 1 micron copper layer can

be plated per minute

Can shorten plating time and increase production capacity





Brightener consumption

is low, durable and


Source manufacturer, concentrated low consumption
