Silver plating
Gold and
Gold Alloys :
Aurostar
Co : Gold- Cobalt alloy process
- Excellent hardness ( 150
VHN )
- Operates at room temperature
- Faster speed of depostion
( 1 microns in 3:30 min )
- Uniform 2N - 3 N rich colour
- Suitable for Jewellary and
PCB / electronics connectors

(0.3 to 0.5 gms /lit )
Aurostrike
DT
- Decorative and Technical
applications
- Available in Ni or Cobalt
alloying formulation
- Offers depassivating effect
enhancing the further depsoit bonding
- Intermdediate bath
- Increases the main gold
bath life
Silver Plating
Silver-marc
Ag 120
- Produces white, bright silver
deposits
- Can be used for depositing
matt silver
- Excellent for decorative
jewellary
- The desposit obtained can
also be used for electrical and electronics applications
- Two component brightner
system
- Suitable for rack and barrel
applications
- Exceptionally high throwing
power
Palladium
Plating
Palla-marc Pd
- 202
- Bright deposit
- Can be used as a final finish
or as a passive diffusion barrier undecoat for Gold plating
- Suitable for electronics
applications
Silver Antitarnish
Anti Tar
Ag
- Organic molecule specially
designed to protect electroplated Silver surface from
tarnishing in all the atmospheric conditions
- Immersion process operated
at room temperature
- Does not require baking
after application just simply dry.
- The organic molecule forms
the bond with the silve surface providing a barrier between
the atmosphere and hence the process is far different
from organic lacquers.
- Water base suspention uniformly
reaches all over to components.
- Requires contineous solution
agitation to achieve exceptionally good results
Undercoats
Bronze Plating
Decorative
Yellow Bronze
- Decorative colour resembling
to 2 N gold colour
- Very effective as an undercoat
for decorative gold plating
- Makes gold plating economic
by reducing the required thickness of Gold
- Hard deposit ( hardness
value up top 350 VHN )
- Can be used as repacement
for bright nickel ( Nickel free jewellary)
- Easy to operate ( supported
by Units additions based on Amp-Min )
Decorative
White Bronze
- White colour , suitable
as undercoat for Silver as well as final finish for jewellary
- Excellent hardness ( upto
350 VHN )
- Good wear resistance
